AM18X5系列系统电源管理应用说明书
1.IntroductionIn addition to fundamentally low power RTC operation, the Ambiq AM18X5 includes the capability to effectively manage the power of other devices in a system. This allows the creation of extremely power efficient systems with minimal additional components. This Application Note describes how the AM18X5 may be used in various applications.2.System Power Control ApplicationsThe AM18X5 enables a variety of system implementations in which the AM18X5 can control the power used by other elements in the system. This configuration is typically used when the entire system is powered from a battery and minimizing total power usage is critical.2.1VSS Power SwitchedFigure 1 shows the recommended implementation, in which the internal power switch of the AM18X5 is used to completely turn off the MCU and/or other system elements. In this case the PSW/nIRQ2 output is configured to generate the SLEEP function, and the PWR2 bit is asserted. Under normal circumstances, the PSW/nIRQ2 pin is pulled to VSS with ~1 ohm of resistance, so that the MCU receives full power. The MCU initiates a SLP operation, and when the AM18X5 enters the SLEEP state the PSW/nIRQ2 pin is opened and power is completely removed from the MCU. This results in significant additional power savings relative to the other alternatives because even very low power MCUs require more current in their lowest power state than the AM18X5.The AM18X5 normally powers up selecting the OUTB register bit to drive the PSW/nIRQ2 pin, and the default value of the OUTB bit is zero. This ensures that the power switch is enabled at power up. If the power switch function is used, software should only change the PSW/nIRQ2 selection between OUTB (0b111) and SLEEP(0b110) to ensure no glitches occur in the power switching function.Figure 1 – Switched VSS Power Control2.2 VCC Power SwitchedFigure 2 shows the application in which an external transistor switch T is used to turn off power to the MCU. The SLP function operates identically to the VSS switched case above, but this implementation allows switchinghigher current and maintains a common ground. R can be on the order of megohms, so that negligible current is drawn when the circuit is active and PSW/nIRQ2 is low.Figure 2 – Switched VCC Power Control2.3 Reset DrivenFigure 3 shows the application in which the AM18X5 communicates with the system MCU using the reset function. In this case the MCU initiates a SLP operation, and sets the SLRES bit so that when the AM18X5enters the SLEEP state, it brings nRST low to reset the MCU. When the trigger occurs, the AM18X5 releases the MCU from reset, and may also generate an interrupt which the MCU can query to determine how reset wasexited. Since many MCUs use much less power when reset, this implementation can save some system power.Figure 3 – Reset Driven Power ControlOne potential issue with this approach is that many MCUs include internal pullup resistors on their reset inputs, and the current drawn through that resistor when the reset input is held low is generally much higher than theMCU would draw in its inactive state. Any pullup resistor should be disabled and the nRST output of the AM18X5 should be configured as a push-pull output.2.4Interrupt DrivenFigure 4 shows the simplest application, in which the AM18X5 communicates with the system MCU using an interrupt. The MCU can go into standby mode, reducing power somewhat, until the AM18X5 generates an interrupt based on an alarm or a timer function. This produces smaller power savings than other alternatives, but allows the MCU to wake in the shortest time.Figure 4 – Interrupt Driven Power Control3.Sleep RegisterThe register which controls the Sleep function of the Power Management system in the AM18X5 is the Sleep Register, accessed at register offset 0x17. The bits of the Sleep Register are defined below.SLP [7] - when 1, the Power Control State Machine (SM) described in Section 4will transition to theSWAIT state. This bit will be cleared when the SM returns to the RUN state. If either STOP is 1 or no interrupt is enabled, SLP will remain at 0 even after an attempt to set it to 1.SLRES [6] - when 1, assert nRST low when the Power Control SM is in the SLEEP state.EX2P [5] - when 1, the external interrupt XT2 will trigger on a rising edge of the WDI pin. When 0, the external interrupt XT2 will trigger on a falling edge of the WDI pin.EX1P [4] - when 1, the external interrupt XT1 will trigger on a rising edge of the EXTI pin. When 0, the external interrupt XT1 will trigger on a falling edge of the EXTI pin.SLST [3] - set when the AM18X5 enters Sleep Mode. This allows software to determine if a SLEEP has occurred since the last time this bit was read.SLTO [2:0] - the number of 7.8 ms periods after SLP is set until the Power Control SM goes into theSLEEP state. If SLTO is not 0, the actual delay is guaranteed to be between SLTO and (SLTO - 1)periods. If SLTO is 0, the transition will occur with no delay.4.Sleep Control State MachineThe AM18X5 includes a sophisticated Sleep Control system that allows the AM18X5 to manage power for other chips in a system. The Sleep Control system provides two outputs which may be used for system power control:1) A reset (nRST) using the nRST output pin may be generated to put any host controller into a minimumpower mode and to control sequencing during power up and power down operations.2) A power switch signal may be generated (PWR), which allows the AM18X5 to completely power downother chips in a system by allowing the PSW/nIRQ2 pin to float. The OUT2S field must be set to a value of 6 to select the SLEEP output. When using the PWR output, PSW/nIRQ2 is configured as an opendrain pin with 1 ohm resistance. This allows the AM18X5 to directly switch up to 50 mA of current with no external components or to control a single external transistor for higher current switching. The lowresistance power switch is enabled by setting the PWR2 bit. If the I2C or SPI master (i.e., the hostcontroller) is powered down by the power switch, the PWGT bit should be set to ensure that a floating bus does not corrupt the AM18X5.3) If OUT2S is 6, but the PWR2 bit is not set, PSW/nIRQ2 will be configured as a high true Sleep outputwhich may be used as an interrupt.The Sleep state machine in Figure 5 receives several inputs which it uses to determine the current Sleep State:1) POR – the indicator that power is valid, i.e. either VCC or VBAT is above the minimum voltage.2) SLP - the Sleep Request signal which is generated by a software access to the Sleep Register.3) TRIG - the OR of the enabled interrupt request from the Alarm comparison in the RTC, the interrupt signalfrom the Countdown Timer in the RTC, the interrupt signal from the Watchdog Timer in the RTC, theExternal Interrupt 1 or 2 pins, the Battery Low detection interrupt, the Autocalibration Fail interrupt, or the Oscillator Fail interrupt.4) TO - the timeout signal from the SL Timeout counter.4.1RUNRUN is the normal operating state of the AM18X5. PWR and nRST are not asserted, SLP is 0, and SLST holds the state of the previous Sleep. SLST should be cleared by software before entering the SWAIT state.4.2SWAITSoftware can put the chip to sleep by setting the SLP bit in the Sleep Register, as long as a valid interrupt is enabled (see Section 4.4) indicated by VAL being asserted. The SM moves to the SWAIT state and waits for a programmable number of seconds (0 to 7) selected by the SLTO field in the Sleep Register. This allows software to perform additional cleanup functions after setting SLP before the MCU is shut down. Operation is the same in SWAIT as it is in RUN, and if an enabled interrupt occurs (TRIG) the SM returns to the RUN state and clears the SLP bit. PWR and nRST are not asserted, SLP is 1, and SLST is 0.4.3SLEEPOnce the programmed number of seconds has elapsed in the SWAIT state, the TO signal is asserted and the machine moves to the SLEEP state, putting the AM18X5 into Sleep Mode. In this case the PWR signal is removed, and nRST is asserted if SLRES is set. Once an enabled operational interrupt occurs (TRIG), the SM returns to the RUN state, reactivates power and removes reset as appropriate. The SLST register bit in the Sleep Register is set when the SLEEP state is entered, allowing software to determine if a SLEEP has occurred.!POR!TO * !TRIG!SLP + !VAL!TRIGFigure 5 – Sleep State Machine4.4 SLP ProtectionSince going into Sleep Mode may prevent an MCU from accessing the AM18X5, it is critical to ensure that the AM18X5 will receive a TRIG signal. To guarantee this, the SLP signal cannot be set unless the STOP bit is 0 and at least one of the following conditions exists:1) The AIE bit is 1, enabling an Alarm interrupt.2) The TIE and the TE bits are 1, enabling a Countdown Timer interrupt. 3) Either the EX1E or EX2E bit is a 1, enabling an External interrupt.4) The BMB field is not zero and the WDS bit is zero, enabling a Watchdog InterruptIn addition, SLP cannot be set if there is an interrupt pending. Software should read the SLP bit after attempting to set it. If SLP is not asserted, the attempt to set SLP was unsuccessful either because a correct trigger was not enabled or because an interrupt was already pending. Software must correct the situation before attempting to enter Sleep Mode again.5.Typical System ImplementationFigure 6 is a more detailed view of a typical system using the VSS Power Switched approach. The VSS pin of the MCU, and potentially other system components, is switched using the PSW pin of the AM18X5. The nIRQ pin of the AM18X5 is connected to an interrupt input of the MCU, allowing the MCU to utilize the RTC interrupt functions of the AM18X5 when it is awake. The nRST output of the AM18X5 is connected to the reset input of the MCU, enabling the AM18X5 to control power on reset and integrate an external MCU reset button RESET. The MCU controls the AM18X5 over a SPI or I2C I/O channel.Figure 6 – System ExampleThe key value of the AM18X5 in this type of system is the ability to put the MCU into an off state, and providing a very rich variety of triggers which can cause the AM18X5 to wake the MCU from the off state. There are a number of different triggers which may be useful.5.1AlarmsThe system may require the MCU to wake up at particular times, which is accomplished by configuring the Alarm Interrupt function of the AM18X5.5.2Countdown TimerThe system may require the MCU to wake up at periodic intervals which do not necessarily correspond to specific calendar times. The Countdown Timer of the AM18X5 provides highly flexible time interval configuration to support this function.5.3WAKE Button/SwitchA very common requirement is the capability to wake the system with a manual input such as a pushbutton or switch, typified by the WAKE button in Figure 6. One of the external interrupt inputs such as EXTI may be simply connected to the button. All AM18X5 inputs include Schmitt trigger circuitry to enable clean interrupts. If additional debouncing of the input is required, the AM18X5 provides direct access to the interrupt input pins to facilitate software implementations.5.4External Device InputsIn some systems an external device such as a wakeup radio may provide a signal which must wake the MCU. An AM18X5 external interrupt such as the WDI pin provides this capability.5.5Analog InputsSome systems include analog signals, such as light sensors or detectors on radio antennas, which must wake the MCU. The Analog Comparator function, which allows the voltage on the VBAT input of the AM18X5 to be compared with a configurable voltage threshold and generate an interrupt, can easily be used in this application, and it allows flexible configuration, both in voltage levels and in transition direction to support different environments. The Analog Comparator may also be used to provide a third external digital interrupt if necessary by selecting the proper digital threshold.5.6Battery Low DetectionThe Analog Comparator can provide a battery low detection function. In this case, the VCC pin would be tied to the VBAT pin, and the thresholds would be adjusted to ensure that the Battery Low interrupt occurs prior to any Brownout Detection on the VCC input. This allows software to prepare for a potential battery failure in advance without having to poll the battery level.5.7ErrorsAny failure interrupt in the AM18X5 may also be configured to wake the MCU. This can be particularly valuable for Oscillator Failure detection, when software may need to respond to the error in order to report the problem quickly.6.Saving ParametersIf the MCU is powered down in Sleep Mode, there is often some data which must be preserved until the next power up. The internal RAM of the AM18X5 is always available, so software can easily save any necessary parameters prior to entering Sleep Mode and retrieve them when the MCU wakes up.7.Power Switch Electrical CharacteristicsThe power switch on the AM18X5 PSW pin has a typical on resistance of 1 ohm over the full temperature range so that currents up to 50 mA may be handled without appreciable voltage drop. This allows the AM18X5 to switch power to multiple devices in most systems, which can be particularly important for components without internal Sleep functions. If the PSW pin is not used as a power switch, the maximum leakage current of the ~1 Ω switch is less than 250 pA at 25 °C.8.Avoiding Unexpected Leakage PathsOne potential problem which can occur when the AM18X5 powers other devices down is that unexpected leakage paths can be created between the powered AM18X5 and the unpowered device. The AM18X5 can be configured to disable inputs and outputs in Sleep Mode to prevent leakage. In general, any input or output pin connected to a device which is powered down should be disabled. Any pins which remain powered in Sleep Mode, such as pushbutton inputs used to wake the system, must not be disabled.1) nRST is disabled in Sleep Mode by clearing the RSEN bit in the Output Control Register.2) FOUT/nIRQ is disabled in Sleep Mode by clearing the O1EN bit in the Output Control Register.3) CLKOUT/nIRQ3 is disabled in Sleep Mode by clearing the O4EN bit in the Output Control Register.4) nTIRQ (I2C devices only) is disabled in Sleep Mode by clearing the O3EN bit in the Output ControlRegister.5) EXTI is disabled in Sleep Mode by setting the EXDS bit in the Output Control Register.6) WDI is disabled in Sleep Mode by setting the WDDS bit in the Output Control Register.7) The I2C or SPI interface pins are disabled in Sleep Mode by setting the PWGT bit in the Oscillator ControlRegister. This is a particularly important function because there are multiple leakage paths in the I/Ointerfaces.9.System Power AnalysisThe AM18X5 can significantly improve the power characteristics of many different types of systems. A specific example will be presented, and several other generalizations can be made from this. The fundamental advantage provided by the AM18X5 is that it allows the system designer to essentially ignore the sleep current of other system components, which allows the utilization of components which have be optimized for other parameters, such as active power, cost or functionality.9.1Using an External RTC with Power ManagementThe key element in any system power analysis is the usage profile, and for this example we assume the system is active for T act and inactive for T inact. I act is the current drawn when the system is active, and I inact is the current drawn when the system is inactive. The average current I avg is therefore:I avg = (T act * I act + T inact * I inact )/(T act + T inact)An example will use a PIC16LF1947 MCU, which is highly optimized for low power operation. This MCU draws 80 nA in Sleep Mode, 1.8 uA in Sleep Mode with the internal oscillator and RTC active, and 120 uA in 500 KHz active mode. Assume a usage profile where the system in active for 1 second every 30 minutes, so that T act is 1 and T inact is 1799. If this MCU is used alone and supplies the RTC functions, the average current for theusage profile is:I avg = (1 * 120 uA + 1799* 1.8 uA)/1800 = 1.865 uAIf the AM18X5 is used to provide the RTC functionality in Autocalibrated RC Mode (<20 nA continuous current) and the PIC is placed into Sleep Mode, the average current for the usage profile is dramatically lower:I avg = (1 * 120 uA + 1799* 80 nA)/1800 + 20 nA = 166 nAThis is a significant improvement, but the current can be further reduced by having the AM18X5 switch power to the MCU. The resulting average current is ~50% lower:I avg = (1 * 120 uA + 1799* 0 nA)/1800 + 20 nA = 86 nA9.2Managing MCU Active PowerIn many cases, the duration of the active time is a function of how much processing must be accomplished, and can therefore be assumed to be a linear function of the MCU clock frequency in active mode. The examples in the previous section assumed that the MCU ran for 1 second at 500 KHz, so 500,000 cycles of an 8-bit processor were required. Like most MCUs, the PIC has a relatively constant active current as a function of clock frequency, so using a higher internal frequency in the same MCU would have little effect on the overall power. However, there may be other MCUs (such as those with 32-bit processors) which have better active power efficiency but poor sleep power, and power switching with the AM18X5 eliminates any sleep power considerations.9.3Lower Cost MCUsLower cost MCUs often have poor sleep power characteristics relative to sleep optimized parts. Since theAM18X5 eliminates sleep power considerations, these lower cost processors may provide equivalent overall average power at significant cost savings.9.4High Performance ProcessorsIn some applications very high performance processors such as DSPs must be used due to real time processing requirements. These processors are generally not optimized for sleep performance, but they may be used in applications with low duty cycles. One example of this is fingerprint recognition, which is rarely accessed but must provide very fast response with complex processing. The AM18X5 power management functions enable a system design where the processor is powered down the vast majority of the time, providing low average power combined with very high instantaneous performance.Document Revision HistoryRev # Description0.01 Initial version0.02 Add leakage management0.03 Corrected calculations in section 9.10.04 Updated doc to only reflect the AM18X5 part numbersAddress:Ambiq Micro, Inc.11305 Four Points Drive, Building 2, Suite 250Austin, TX 78726+1-512-879-2850Website:General Information:*******************Sales:********************Technical Support:**********************。

Presentation演讲实例
Early visions of wireless power actually were thought of by Nikola Tesla basically about 100 years ago. And so, in fact, he actually set about doing a variety of things. Built the Tesla coil. This tower was built on Long Island back at the beginning of the 1900s. And the idea was, it was supposed to be able to transfer power anywhere on Earth. We'll never know if this stuff worked. Actually, I think the Federal Bureau of Investigation took it down for security purposes, sometime in the early 1900s.Bad news？Creative ideas that this tesla coil becomes the staples of soviet military installation.The electricity out can devastate the enemy infantry and proved almost as effective on most vehicles.Let’s back to the theme.The one thing that did come out of electricity is that we love this thingso much.I mean,think about how much we love it.If you just walk outside,there are infinite dollars have been invested in infrastructure around the world, putting up wires to get power from where it's created to where it's used. The other thing is, we love batteries.However,for those of us that has environmental pollution to our world,there is something like 40 billion disposable batteries built every year for power that. Do you ever wonder what happens to this stuff? 40 billion of these things built. This is what happens. They fall apart, they disintegrate, and they end up here.Without a battery,we need a wire for electricit though.Whereas,bad experience would still be thereWe've all dealt with wire jungles behind our computers and televisions. They just crop up, a natural tangle of cords formed by the devices we connect to each other. It's just a reality of modern technology. However, they can be more than simply inconvenient; large cable tangles can be detrimental to certain electronics' performance, and in extreme cases can be outright dangerous.Besides the risk of fire and electrical short, a tangle of power cables can potentially damage your electronics through unwanted power loss (that is, unexpectedly yanking a power cable out of the wall).There is another problem with interference.Analog signals sent over cables, like audio piped out from an receiver to speakers, can get interference from strong electrical currents, like power cables. An audible buzz can be heard when placing speaker cables (or any other analog audio cable) within a few inches of a live power cable.So ,think about it.Waking up at night to the third night in a row that his wife's cellphone was beeping because it was running out of battery power. And he was thinking, "With all the electricity that's out there in the walls, why couldn't some of that just come into the phone so I could get some sleep?"He is Dr.Soljacic,the theretical physicist at MIT,coming up with the concept of tranferring the electricity over distance.Basically they were able to light a 60 watt light bulb at a distance of about two meters. It got about 50 percent of the efficiency -- by the way, that's still a couple thousand times more efficient than a battery would be, to do the same thing. This was actually the experiment. So you can see the coils were somewhat larger. The light bulb was a fairly simple task.But he were able to light that, and do it very successfully.So how does it work?Imagine a coil. For those of you that are engineers, there's a capacitor attached to it too. And if you can cause that coil to resonate, what will happen is it will pulse at alternating current frequencies -- at a fairly high frequency, by the way. And if you can bring another device close enough to the source, that will only work at exactly that frequency, you can actually get them to do what's called strongly couple, and transfer magnetic energy between them. And then what you do is, you start out with electricity, turn it into magnetic field, take that magnetic field, turn it back into electricity, and then you can use it.Okay,you may have the question that is this system be able to exchange the different power between different objects.Let’s move on to the evidence for that.The amount of wine in the glass affected its resonant frequency by singer’s voice performing in a room filled with wine glasses.Only when absorbed enough energy from sound waves in the air it was to be shattered –while the other glasses remained unharmed.In this example, energy is transferred very efficiently between sound waves in the air and the mechanical vibrations of the glass, at the partially filled wine glass’resonant frequency.。

英语presentation自我介绍
英语presentation自我介绍全文共6篇示例，供读者参考篇1Hi everyone! My name is Emily and I'm 8 years old. I'm really excited to tell you all about myself today.I live with my mom, dad, and little brother Charlie who is 5. We have a dog named Buddy who is a Golden Retriever. He's really cute and fluffy and loves to play fetch. My favorite game is hide and seek - I'm really good at finding the best hiding spots!In my free time, I love playing outside. My friends and I have a awesome treehouse in my backyard that my dad built for us. We love having picnics up there and putting on little plays. I'm usually the director because I like being in charge. Sometimes we get a little too rowdy though and my mom has to tell us to keep it down.I'm also on a soccer team called the Red Rockets. I play defense because I'm really fast. My teammates are a lot of fun and we always go for ice cream after our games. Chocolate is my favorite flavor! I'm not very good at scoring goals yet, but I'm getting better at kicking the ball every practice.In school, my favorite subjects are art and reading. I love drawing pictures of animals and mythical creatures like unicorns and dragons. Reading takes me to such amazing make-believe worlds full of adventures. I get totally lost in books sometimes and have to be called for dinner several times before I snap out of it!My least favorite subject is math because I find it really confusing and boring. All those numbers and equations just make my brain feel like mush. I have to work really hard on my math homework but my mom is a good teacher and helps me understand it better. I'm getting a little better at it, but it's still not my favorite.One of the coolest things about me is that I was born on Christmas Day! Every year my birthday party has a holiday theme and we get to decorate a tree. Sometimes my friends are traveling to see family though, so then we have to postpone my party until after the New Year. I don't mind though because that means I get two celebration days instead of just one!Another fun fact is that I'm learning to play the violin this year. It's much harder than it looks to make nice sounds come out of that tiny stringed instrument. I have to practice every day and I'm already sick of my beginner songs like "Twinkle TwinkleLittle Star." Hopefully I'll get better soon so I can learn more exciting pieces.My biggest dream is to become a zookeeper when I grow up.I love all kinds of animals, but especially the bigger ones like elephants, giraffes, and tigers. Can you imagine getting to hang out with those amazing creatures every day? Getting to feed them, clean their habitats, and make sure they are healthy sounds like the coolest job ever to me. I definitely don't want to be stuck behind a desk all day long like my dad. Ugh, how boring would that be?Well, that's about all I can think to share right now. Let me know if you have any other questions for me! I may be little, but I've got a big personality.篇2Hi everyone! My name is Michael and I'm 10 years old. I'm in the 5th grade at Oakwood Elementary School. Today I'm going to tell you all about myself!First, let me tell you about my family. I live with my mom, dad, and little sister Emily who is 7 years old. My mom's name is Sarah and she works as a nurse at the hospital downtown. My dad's name is Robert and he's an accountant at a big company.We also have a dog named Buddy who is a golden retriever. He's really friendly and loves to play fetch!At home, I have my own bedroom that I share with no one. My favorite part is all the LEGOs I have - I love building cool spaceships, cars, and buildings with them. I also like reading comic books, playing video games, and watching superhero movies. My favorite superhero is Spider-Man because he's so strong and can climb up walls and swing through the city!In school, my favorite subjects are math and science. I'm really good at solving math problems and I find the science experiments we do to be really fun and interesting. My least favorite is writing though - I find it kind of boring to just sit there and write sentences for a long time. I much prefer the more hands-on stuff.I have a pretty good group of friends at school篇3Hello everyone! My name is Lucy and I am so excited to be here today to introduce myself.First of all, let me tell you a little bit about myself. I am 10 years old and I am in the fifth grade.

He is my best friend, and we love to go for walks together.One of my dreams is to become a teacher when I grow up. I love helping others and sharing my knowledge with them. I think teachers are superheroes because they can inspire and guide us to become better people. I also want to travel around the world and learn about different cultures. It would be so exciting to see famous landmarks like the Eiffel Tower in Paris or the Great Wall of China.I am a very active person, and I enjoy participating in sports. I am a member of the school's basketball team, and we practice every week. I also take swimming lessons on the weekends. Swimming is so much fun, and it helps me stay fit and healthy. I believe that sports teach us important values like teamwork, discipline, and perseverance.Besides sports, I am also involved in some extracurricular activities at school. I am part of the school choir, and we perform at different events throughout the year. Singing brings me joy, and it makes me feel happy to see people smiling when we perform. I also take art classes, and I like to express my creativity through drawing and painting.In conclusion, I am a friendly and curious girl who loves learning, helping others, and being active. I believe that every day is an opportunity to grow and discover new things. I am excited to be here today and to meet all of you. Thank you for listening to my presentation. If you have any questions, please feel free to ask.篇4Hello everyone! My name is Lily, and I am so excited to stand here and introduce myself to all of you. I am a happy and enthusiastic little girl who loves learning new things and making new friends. Today, I am going to tell you a little bit about myself.First of all, let me start by telling you how old I am. I am eight years old and I am currently studying in the third grade. My favorite subject in school is English because I love reading andwriting stories. I also enjoy learning about different countries and their cultures.In my free time, I have many hobbies that keep me busy and entertained. One of my favorite hobbies is drawing. I love to express my imagination and create colorful drawings. I also enjoy playing the piano. It's so much fun to learn new songs and play them with my friends and family. Besides that, I like playing outdoor games like tag and hide-and-seek with my friends. It's a great way to stay active and have fun at the same time.When it comes to my family, I have a wonderful and supportive one. I live with my mom, dad, and my little brother. My mom is a teacher, and my dad is a doctor. They always encourage me to do my best and follow my dreams. My little brother, Jack, is four years old, and he can be a bit mischievous, but I still love him a lot.One of the things that makes me really happy is making new friends. I believe that friends are like stars that brighten up our lives. I am always eager to meet new people and learn about their interests and hobbies. I think it's important to be kind and helpful to others, and I try my best to be a good friend to everyone around me.In the future, I have big dreams and goals. I want to become a writer and publish my own books. I love to create stories and characters that can inspire others. I also want to travel around the world and learn about different cultures firsthand. There are so many beautiful places to explore, and I can't wait to see them all.In conclusion, I am Lily, an enthusiastic and friendly little girl who loves learning, making friends, and exploring new things. I hope you enjoyed getting to know me a little better. Thank you for listening to my presentation!篇5Hello everyone! My name is Emma and I'm really excited to tell you all about myself today. I just turned 9 years old last month. I have long brown hair and green eyes. My mom says I'm getting so tall - I'm already one of the tallest kids in my 4th grade class!I live with my mom, dad, and little brother Charlie who is 6 years old. We also have a dog named Buddy who is a golden retriever. He's really fun to play with in our backyard. We like to play fetch and sometimes I even let him catch the frisbee in his mouth!My favorite subject in school is math because I think it's really interesting to solve problems and number puzzles. Reading is fun too though, especially books with adventure stories or mysteries to figure out. My least favorite is probably science because I don't like dissecting things or doing experiments with gross stuff.Outside of school, I really love playing sports! Soccer is my absolute favorite sport. I've been playing on a local recreation team since I was 6 years old. I love running up and down the field and trying to score goals. I'm one of the fastest players on my team. I also enjoy basketball, softball, and swimming in the summer.Some of my other hobbies are drawing, listening to music, and watching movies. I'm a really good artist and love using colored pencils or markers to draw pictures of animals, outer space scenes, or just doodling patterns. My favorite singers are Taylor Swift and Billie Eilish - I know all the words to their popular songs! For movies, I like animated films like Frozen or live-action comedies that make me laugh.My family is really important to me. We always eat dinner together and I help my mom set the table. Then we go around and share the best part of our day. I love spending time with myparents and little brother. On weekends, we sometimes go bowling, roller skating, or to the park for a picnic lunch.Last summer, we went on a really fun family vacation to the beach for a week. It was my first time seeing the ocean! I loved building sandcastles, collecting seashells, and swimming in the waves. We also went mini golfing a few times which I'm pretty good at. And we watched fireworks on the 4th of July which was amazing.When I grow up, I think I might want to be a teacher or maybe even a scientist after all. I love learning new things every day. Or maybe I'll become a professional soccer player - that would be so cool! For now though, I'm just enjoying being a kid. Playing with my friends at recess, having sleepovers on weekends, and not having too many responsibilities.That's about it for me - thanks for listening everyone! I'll finish by sharing some of my favorite things: my favorite food is pizza (pepperoni is the best!), my favorite color is purple, my favorite animal is a dolphin, and my favorite holiday is Christmas because I love the decorations and getting presents. Let me know if you have any other questions!篇6Hi everyone! My name is Emma and I'm 8 years old. I'm really excited to tell you all about myself today.First, I want to tell you about my family. I live with my mom, dad, and little brother Charlie who is 5 years old. My mom's name is Sarah and she works as a nurse at the hospital. My dad's name is Michael and he's a teacher at the middle school. We also have a dog named Buddy who is a golden retriever. He's really cute and furry and loves to play fetch!At home, my favorite thing to do is play pretend with my brother. We have so much fun using our imaginations. Sometimes we pretend to be explorers going on adventures in the jungle. Other times we'll pretend to run a restaurant and cook make-believe food for our parents. It's really silly but we laugh so much.I also love arts and crafts. My favorite is making friendship bracelets out of embroidery floss. I can make all sorts of cool patterns and designs. I give them to my friends and they give me bracelets too. We trade them like treasures!In school, my favorite subjects are art class and storytime. I love getting messy with the paints, markers, and clay. And when we have storytime, our teacher Mrs. Thompson has the best voices for all the characters. I can listen to her read for hours!Here's a fun fact about me - my favorite food is pizza! I could eat it every single day. My favorite toppings are pepperoni, sausage, and extra cheese. Sometimes I even put ranch dressing on my pizza which my brother thinks is really gross. But I love it!My favorite holidays are Halloween and Christmas. For Halloween, I love dressing up in fun costumes and getting lots。

DPF is used to measure the effect o€ inductive(motor, transformer( and capacitive loads on the efficiency of an ac distribution system. Such loadshave a reactive component (see VARs) which must be taken into account when sizing systemcapacity, but they are still linear loads (current is drawn as a sine wave). DPF therefore does notinclude the effect of non-linear harmonic currents, However, a low DPF will often result in extrademand charges by utilities.PF Power Factor or Total Power Factor. Active Power divided by Apparent Power. PF is ameasurement of the efficiency of an ac power transmission and distribution system, including theeffects of harmonics (as well as VARs). Harmonic currents cause PF to be lower than DPF.%THD-F Percent Total Harmonic Distortion-Fundamental reference. This readingrepresents the ratio of the harmonic components of voltage lot current) to the voltage (or current)of the fundamental alone. All measurements are true-rms.O/oTHD-R Percent Total Harmonic Distortion-HMS reference. This reading represents theratio of the harmonic components of voltage (or current) to the total voltage (or current), includingthe fundamental and all harmonics. All measurements are true-rns.(k)W(kilo)Watts. Active power, also known as Real/True Power. Watts measure that portion ofelectrical power which does work, which by definition includes heat losses. Utility charges arebased on Watts.(k)VA(kilo) Volt-Amperes. Apparent power. VA is computed by taking the product of the rmsvalues of voltage and current, It is a measure of the total electrical power capacity of a distributionsystem or component equipment. In addition to Watts, it includes the contributions of VARs andharmonic currents. This term is of interest because utility and facility engineers must size theirsystem equipment in VA, in effect providing the current-carrying capacity to handle the worst-case situation.(k)VAR(kilo) Volt-Amps Reactive. Reactive Power. VARs are the reactive component of VA(Apparent Power), caused by a phase shift between ac current and voltage in inductors (coils) andcapacitors. In inductors, current lags voltage (in time), while in capacitors, current leads voltage.VARs are typically first present in a distribution system as a result of inductive loads such asmotors, reactors and transformers. VARs are then used in sizing power factor correctioncapacitors, which are used to offset the effects of these inductive loads.。

英文简历自我评价2Dear HR,My name is On May 25, 1989, I was born in Xinying, a little town in Southern Fujian. My father is a farmer, planting bananas and pineapples, and my mother takes care of the house. I have two brothers and one sister. Though not well-to-do, my parents have been able to provide the whole family with sufficient means to live decently and enjoy all modern conveniences.My early education was received in my hometown, i.e. six years in primary school and three years in junior middle school. After completing nine years of formal education in 1958. I went to Xiamen and participated in the joint entrance examination for five-year junior colleges. Fortunately, I was admitted to the Department of Electrical Engineering at Xiamen Junior Engineering College. I chose Electrical Engineering asmy major because, on the one hand , I liked Physics very much; and on the other hand, electrical industry is a major sector of the economy of China.The five years of intensive training came to an end in June 1978 when I received a diploma. And in July 1980. I was hired by Nan Ya plastic Company and have served as a junior electrical engineer at the company to the present. I enjoy the work and feel competent for the job.In working, however, Ive Found that what I have learned in school is limited and far from sufficient to handle sophisticated jobs. Therefore, I have decided to extend my education and would like to enter an American institution firstly to earn a Bachelors degree in Electrical Engineering. Then, if possible, I would like to continue my education toward a Masters degree.After this objective is reached, I will return to my country and seek a job in a public firm. Most probably I will continue to work with Nan Ya Plastic Company.英文简历自我评价3自我评价是紧紧围绕着所应聘的职位展开，向招聘人员展示你与该职位非常匹配，您的技能和资质与所应聘的职位相符，是该职位的不二人选。
