TP4054 线性锂离子电池充电器
描述
TP4054 是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其 SOT 封装与较少的外部元件数目使得 TP4054 成为便携式应用的理想选择。 TP4054 可以适合 USB 电源和适配器电源工作。 由于采用了内部 PMOSFET 架构，加上防倒充电路，所以不需要外部检测电阻器和 隔离二极管。热反馈可对充电电流进行调节，以便在大功率操作或高环境温度条件下对 芯片温度加以限制。 充电电压固定于 4.2V， 而充电电流可通过一个电阻器进行外部设置。 当充电电流在达到最终浮充电压之后降至设定值 1/10 时， TP4054 将自动终止充电循环。 当输入电压（交流适配器或 USB 电源）被拿掉时，TP4054 自动进入一个低电流状 态，将电池漏电流降至 2uA 以下。也可将 TP4054 置于停机模式，以而将供电电流降至 45uA。TP4054 的其他特点包括充电电流监控器、欠压闭锁、自动再充电和一个用于指 示充电结束和输入电压接入的状态引脚。

Dranetz HDPQ Guide instruments are perfec t for applic ations suc h as PQ surveys, fault rec ording, inrush, motor testing, harmonic analysis, advanced distortion analysis, demand/energy/load studies, and much more. The HDPQ Guide and Guide SP offer the exact same measure-ment features, but in different enc losures that c an meet the needs of a wide variety of applications and work environments. The HDPQ Guide is a portable instrument with a built in 7”, Tablet like LCD display. The same local user interface is also available remotely on a PC, Tablet or Smartphone by using the built in Ethernet or Wi-Fi c ommunic ations and Dran-View 7, or a free VNC remote control App. The HDPQ Guide SP offers the same measurement capabilities and communications, but is housed in an IP65 enclosure without an LCD display, greatly expanding applications into outdoor and harsh environments along with those where an LCD display is undesirable.Advan ced PQ & Energy Capabilities!Dranetz products have a long-standing tradition of having state of the art PQ monitoring capabilities, and the Dranetz HDPQ Guide is no exc eption. HDPQ Guide meets and exc eeds the most stringent industry monitoring standards, including:Power Quality - IEC 61000-4-30 Class A, IEEE 1159Harmonics - IEC 61000-4-7, IEEE 519Voltage Flicker - IEC 61000-4-15, IEEE 1453 – Including Pinst Advanced Energy – IEEE 1459Transient CaptureThe Dranetz HDPQ Guide goes well beyond the requirements of the PQ standards by including transient capture capabilities for voltage and current, such as: transients to 32 microseconds, peak sample transients, and advanced waveshape change tran-sients that can identify changes from cycle to cycle.AnswerModules ® – Smart & Good Looking!Only available from Dranetz, AnswerModules are algorithms that automatic ally identify power quality problems and their sourc e. These diagnostic and reporting tools are based on our decades of analytic al experienc e, benc hmarking, and troubleshooting work. The HDPQ Guide has three built in AnswerModules:Sag/Dip Directivity: Automatically identifies the source of a Sag/Dip as being up stream or downstream from the moni-toring source.Capacitor Switching: Automatically identifies transients as being Power Factor correction transients.Motor Analysis: Enables the PQ p arameters that are imp ortant to motor surveys, and provides a custom dashboard for results.G®The Best Combination of Value & Technology in a PQ Analyzer - Safe, Powerful & IntelligentPower Quality instruments are no different than anything else – you get what you pay for – you just get much more from the Dranetz HDPQ ® Guide than with any other instrument in its class!The Dranetz HDPQ ® Guide SP offers the same value, but in a hardened IP65 enclosure.Safe Remote Accessibility via Dran-View ® 7, Apps and VNCDON’T RISK YOUR SAFETY! The Dranetz HDPQ Guide comes with a standard Ethernet port, built-in Wireless, and USB Bluetooth commu-nications that allow you to easily comply with today’s arc flash and other safety standards. Simply install your HDPQ Guide, close the cabinet door, and use your Tablet, Smartphone, PC, or MAC computer to remotely control monitoring and review data. Fully control your instrument remotely, and see exactly what’s on the local 7” display by using Dranview 7 or a free VNC program or App for PC, MAC, Apple and Android devices. Or, you can also use the Dranetz HDPQ App for Apple and Android devices to remotely view a real-time dashboard, scope mode, or remotely configure the instrument using automatic setups. For local access, there’s also a built-in USB port to copy data to a USB drive or directly to your computer using a Plug-N-Play connection.Dashboard Display Demand & Energy TrendEasy to Use Intuitive User InterfaceWith their innovative packaging and 7” wide screen color touch display, the Dranetz HDPQ family of instruments are the most powerful and easiest to use power monitoring instruments available. Like your tablet computer, simply useyour finger or stylus to easily navigate the intuitive, icon-based user interface. Setting up the HDPQ Guide is made easy with automatic setups that detect the cir-cuit type, voltage, etc. and configure the instrument in seconds with typical indus-try settings. For customized setups, use the manual Wizard mode that guides you step-by-step through each setup. During monitoring, real time measurements can be viewed in many ways, including a color-coded reporting Dashboard, and meter/scope/phasor/harmonics displays. Recorded data can be viewed over time by using the timeline and event list displays, and also by using compliance reports, such as EN 50160.Demand & Energy SurveysManaging energy and reducing related expenses is always of par-amount importance, and in many cases is a corporate mandate. In addition to industry-best power quality monitoring capabilities, all of the Dranetz HDPQ family products also have extensive demand and energy monitoring capabilities for both long and short duration surveys. Unlike other lesser capable instru-ments, there’s more than enough horsepower to perform complete PQ and energy surveys simultaneously – it’s your choice to survey for PQ, Energy, or both. Seeing results is easy when using the energy and demand Dashboard reports that display real time and accumulated readings in a color-coded reporting format. There’s also a billing report that includes your energy rates, including time of use. You can also upload your data to our Dran-View 7 software for viewing, reporting, and printing via PC.Reporting & AnalysisThe Dranetz HDPQ Dashboard takes the guess work out of knowing what the instru-ment has recorded. The Dashboard is a color coded alarm panel with boxes that represent different event types (Sags, Swells, Transients, THD, etc.). Each box shows the real time me-tered values for the event type, and is color coded to indicate if events of that type have been recorded.Dran-View ® 7 is our industry leading Win-dows-based software program that enables power professionals to simply and quickly visualize and analyze power monitoring data. Dran-View enhances the Dranetz HDPQ Visa instruments with its VNC remote control, down-loading, and advanced analytical capabilities. It is successfully used by thousands of customers around the world, and has become the industry leading power management software tool. Dran-View is easy to use, yet adds tremendous value and power to our Dranetz HDPQ family of instruments. Of course Dran-View can trend and list data recorded by the instrument, but it also includes a built in report writer, allows you to embed pictures, provides mathematical analy-sis tools, and even includes a rescue kit to help correct connection mistakes.Dran-View ® 7Dranetz HDPQ Live VNC & DownloadDranetz HDPQ Guide SPIP65 Enclosure - No DisplayDranetz HDPQ GuidePortable with 7” DisplayV & I Connections• 1000V CAT III (600V CAT IV)• AC/DC Differential Voltage & Current Inputs • DRANFLEX CT’s powered by the instrumentInnovative Package & Wide Screen7” color, wide screen touch display. 40% largerthan before - the largest in the industry!G UIDE SG UIDE SP。

COLOURS 教学设计
Book 1 Unit 2 Colours (Period 2)胡茵瑜一、教学内容PEP英语三年级上册第二单元U2 colors第二课时P15.二、教材分析（1）这个单元的话题是谈论物体的颜色, 通过本单元教学，使学生能运用所学英语，正确地描述物体的颜色. 教材设计的理念是通过做中学，让学生在体验、参与、研究这样一种过程中去学习语言，最大限度地增加学生参与的量，让学生在实际运用中感受到语言是实用的，而不是仅仅掌握语言知识和技能。
(2) 本课时主要是通过听、说、读、写、画、演等丰富的语言实践活动，帮助学生获得良好的语音基础、初步培养学生的语感和用英语进行简单日常交流的能力。
但三年级学生对于语言环境的交流还是有一定的难度，所以我利用多媒体课件、直观涂色自己房子、扮演ZOOM等手段进行辅助教学，拓展学生视野，提高学生的学习热情和兴趣。
三．教学目标1. 知识目标：①学会认读颜色的单词red,blue,yellow…和句型“I see… .”.②学生对Let’s learn部分能听懂能说能表演。
2. 技能目标：(1) 学生能运用所学句型进行即兴表演；(2)通过交流，学生能灵活运用英语，提高思维能力。
3. 情感目标：（1）通过在设计自己的房子、角色扮演中渗透知识的学习，让学生做主，发挥自己的想象力，激起学生学英语的浓厚兴趣。
（2）通过小组活动和表演活动，学生学会协助与合作，从而提高学习效果，合作学习的意识得到进一步加强。
四、教学重难点：（1）能对句型进行很好的听、说、演、练；（2）I see red .表颜色的形容词单独作表词时，不能用冠词 a/an 修饰。
四．教学准备多媒体课件，颜色笔，卡片。

北京邮电大学电子电路基础课后答案讲解
2.12如图P2-3(a)所示的电路，试问
1.如果观测到的输出电压波形如图(b)所示，则该失真为何种失真？主要由何种原因造成的？如何调整Rb1来解决？
2.如果观测到的输出电压波形如图(c)所示，则该失真为何种失真？主要由何种原因造成的？如何调整Rb1来解决？
解：图(b)中电压顶部削平，相当于电流底部削平，是截止失真。原因是静态工作点太低，应增大IB，即减小Rb1；
2.中频交流等效电路
3.
4.输出主要产生截止失真，
应增大静态工作电流IBQ，即增大VBB，或减小Rb。
2.14设在图P2-5(a)所示电路中，三极管的输出特性曲线如P2-5(b)所示，RS=500，Rb1=9.3k，Rb2=2.7k，rbb=100，VCC=12V，RE1=100，RE=400，RC=1.5k；三极管的导通电压UD=0.7V、=100。试
解：Q2:UEQ= RE*IE= 500Ω*4mA=2V
UBQ= UEQ+0.7V =2.7V
UBQ= 12V* Rb3/ (Rb1+Rb2+Rb3)=3.4*12/(Rb1+5+3.4)= 2.7V
故Rb1= 6.7 kΩ
又UCEQ=6V=12-4*(RC+0.5)
得RC=1(KΩ)
2.11基本阻容耦合放大电路及三极管输出特性曲线如图P2-2所示，三极管发射极的导通电压UD=0.7V、β＝100，VCC=12V，Rb=282k，RC=RL=1.5k，各电容值足够大，试计算工作点、画出直、交流负载线。
解：
1.16. 根据图P1-8各电路中所测的电压值判断三极管的工作状态（放大、饱和、截止和损坏）。
解：(a)发射极正偏压，集电极反偏压，IC不为零，是放大状态；
