Switching Power SupplySwitching power supply is a voltage conversion circuit, the main work is the step-up and step-down, are widely used in modern electronic products. Always work because the switching transistor in the "on" and "off" state, so called switching power supply. Switching power supply in real terms is an oscillator circuit, the conversion of electrical energy not only used in power circuit, the circuit in other applications are also common, such as LCD backlight circuits, such as fluorescent lamps. Switch the source compared with the transformer high efficiency, good stability, small size and other advantages, disadvantages is the relatively small power, and high-frequency interference on the circuit, circuit complexity, such as easy maintenance.Talking about switching power supply before you familiar with the feedback oscillator circuit transformer, can produce a regular pulse current or voltage of the circuit is called oscillation circuit, transformer feedback oscillator circuit is able to meet these conditions the circuit; it in the basic amplifier circuit with a feedback loop composed of C2, L1 election to form a parallel resonant frequency circuit, the instantaneous power in the circuit turn-VT, this time in the C2, L1, composed of parallel resonant circuits have a very rich harmonic, when the plus parallel resonance frequency and the natural frequency of the same circuit, the circuit to enter a state of oscillation, and VT through L3 feedback to further enlarge the base, and ultimately the formation of a regular pulse current or voltage output to the load RL. Switching power supply is around the transformer and the feedback oscillator circuit design, but the basis of the original increase in the number of protection and control circuits, analysis of our oscillation circuit can be used to analyze the method of switching power supply.Switching Power Supply vibration by way of sub-swing can be dividedinto self-excited and it excited the two, since there is no need for plus-excited self-oscillation signal source, since the excitation can see it as a feedback oscillator circuit transformer, and it is excited is totally dependent on the outside to maintain the oscillation, in the practical application of self-excitation of a comprehensive range of applications. According to the structure of incentives signal classification; can be divided into pulse-width-modulated pulse amplitude modulation and two pulse-width-modulated signal to control the width, that is, frequency, pulse amplitude modulation control signal of the magnitude of the role of the two the same so that oscillation frequency is maintained at within a certain range, to the effect of voltage stability. Winding transformer can be divided into three types in general, a group involved in the primary winding of the oscillation, a group is to maintain the oscillation of the feedback winding, there is a group of the load windings. Household appliances used in switching power supply,after the AC to 220V bridge rectifier, converted into about 300V DC, filter into the transformer is added after the switch to high-frequency oscillations of the collector, feedback winding back to the base to maintain the oscillation circuit, load sensor windings of the electrical signal, by rectification, filtering, the DC voltage regulator has been to provide power to the load. Winding in the provision of electric power load, but also take up the capacity of voltage stability, the theory is then a circuit voltage output voltage sampling devices to monitor the output voltage changes, timely feedback to adjust the oscillation frequency oscillator circuit to achieve the voltage stability The purpose of the circuit in order to avoid interference, the feedback voltage to the oscillator circuit will be isolated optocoupler. Most switches have a standby power circuit, switching power supply in standby mode still oscillating, but the frequency of normal working hours than lower.Some switching power supply are complex, numerous components, many protection and control circuit, in the absence of technical support, maintenance is a headache with the matter. I face this kind of situation is, first of all, I will find the switch and its participation in the external oscillation circuit, it separated from the circuit to see if it met the conditions for oscillation, such as detection bias and whether it is normal, whether positive feedback failure, as well as its own switches, switching power supply has very large protection, after exclusion of the prosecution and load control and protection circuit.the control circuit while output from the sample, with the set standards, then controlled inverter, change its frequency or pulse width output achieve stability, on the other hand, according to test data provided by the circuit by circuit protection identification, Control circuit for the unit for various protection measures.SMPS developments and trends in the United States in 1955 Roje (GH.Roger) invention of the self-excited oscillation push redeem transistor single transformer DC converters, high-frequency conversion is the beginning of control circuit, 1957 United States investigation tournament (Jen Sen) since the invention of the push-pull double Flyback transformers, 1964 American scientists proposes to abolish the frequency transformer series switching power supply scenario, This power to the right size and weight of the decline was a fundamental way. To the 1969 high-power silicon transistor because the pressure increase diode reverse recovery time shortened, and other components improve, and finally turned into a 25 kHz switching power supply.Currently, switching power supply to small, Light volume and the characteristics of high efficiency has been widely used in electronic computer-driven variety of terminal equipment, Communications equipment almost all electronic equipment, the electronic information industryindispensable to the rapid development of a power mode. Currently the market for sale in the switching power supply using bipolar transistors made of 100kHz. use made of 500kHz MOS power, though practical, but its frequency to be further enhanced. To improve the switching frequency, it is necessary to reduce the switching loss, and to reduce the switching loss, you need to have high-speed switching devices. However, the switching speed, will be affected by the circuit inductance and capacitance diode or stored charge arising from the impact of the surge or noise. This will not only affect the surrounding electronic equipment, but also greatly reduce the reliability of the power supply itself. Among them, with the switch to prevent Kai-closed by the voltage surge, it is R-C or L-C Composite bumpers, and the storage charge by the diode current surge caused by the use made of amorphous cores such as magnetic bumper. However, the high frequency of 1 MHz and above, using resonant circuit, Switch to enable the voltage or current through the switch was a sine, which could reduce the switching loss, This can also control the surge occurred. Switches such as resonant mode switching. Currently such SMPS of very active, because this means no significant increase switching speed can theoretically put switching loss fall to zero. and the noise is small, is expected to become high-frequency switching power supply of one of the main ways. At present, many countries in the world are working on several trillion Hz converter practical research.开关电源开关电源是一种电压转换电路，主要的工作内容是升压和降压，广泛应用于现代电子产品。

DC Switching Power Supply Protection TechnologyAbstract: The DC switching power supply protection system, protection system design principles and machine protection measures, an analysis of switching power supply in the range of protected characteristics and its design methodology, introduced a number of practical protection circuit.Keywords: switching power supply protection circuit system designA、IntroductionDC switching regulator used in the price of more expensive high-power switching devices, the control circuit is also more complex, In addition, the load switching regulators are generally used a large number of highly integrated electronic systems installed devices. Transistors and integrated device tolerance electricity, less heat shocks. Switching Regulators therefore should take into account the protection of voltage regulators and load their own safety. Many different types of circuit protection, polarity protection, introduced here, the program protection, over-current protection, over-voltage protection, under-voltage protection and over-temperature protection circuit. Usually chosen to be some combination of protection, constitutes a complete protection system.B、Polarity protectionDC switching regulator input is generally not regulated DC power supply. Operating errors or accidents as a result of the situation will take its wrong polarity; switching power supply will be damaged. Polarity protection purposes, is to make the switching regulator only when the correct polarity is not connected to DC power supply regulator to work at. Connecting a single device can achieve power polarity protection. Since the diode D to flow through switching regulator input total current, this circuit applied in a low-power switching regulator more suitable. Power in the larger occasion,while the polarity protection circuit as a procedure to protect a link, save the power required for polarity protection diodes, power consumption will be reduced. In order to easy to operate, make it easier to identify the correct polarity or not, collect the next light.C、Procedures to protectSwitching power supply circuit is rather complicated, basically can be divided into low-power and high-power part of the control part of the switch. Switch is a high-power transistors, for the protection of the transistor switch is turned on or off power safety, we must first modulator, amplifier and other low-power control circuit. To this end, the boot to ensure the correct procedures. Switching Regulators generally take the input of a small inductor, the input filter capacitor. Moment in the boot, filter capacitor will flow a lot of surge current, the surge current can be several times more than the normal input current. Such a large surge current may contact the general power switch or relay contact melting, and the input fuse. In addition, the capacitor surge current will damage to shorten the life span of premature damage. To this end, the boot should be access to a current limiting resistor, through the current limiting resistor to capacitor charging. In order not to make the current limiting resistor excessive power consumption, thus affecting the normal switching regulator, and the transient process in the boot after a short period then automatically relays it to DC power supply directly to the switching regulator power supply. This circuit switching regulator called a "soft start" circuit.Switching regulator control circuit of the logic components required or op-amp auxiliary power supply. To this end, the auxiliary power supply must be in the switch circuit. This control circuit can be used to ensure the boot. Normal boot process is: to identify the polarity of input power, voltage protection procedures → boot → auxiliary power supply circuit and through current limiting resistor R of the switching regulator input capacitor C →charge modulation switching regulator circuit, → short-circuit current limiting resistor stability switching regulator.In the switching regulator, the machines just because the output capacitance, and charge to the rated output voltage value of the need for a certain period of time. During this time, sampling the output amplifier with low input voltage sampling, closed-loop regulation characteristics of the system will force the switching of the transistor conduction time lengthened, so that switching transistor during this period will tend to continuous conduction, and easily damaged. To this end, the requirements of this paragraph in the boot time, the switch to switch the output modulation circuit transistor base drive signal of the pulse width modulation, can guarantee the switching transistor by the cut-off switches are becoming more and more normal state, therefore the protection of the setting up of a boot to tie in with the soft start.D、Over-current protectionWhen the load short-circuit, overload control circuit failure or unforeseen circumstances, such as would cause the flow of switching voltage regulator transistor current is too large, so that increased power tubes, fever, if there is no over-current protection device, high power switching transistor may be damaged. Therefore, the switching regulator in the over-current protection is commonly used. The most economical way is to use simple fuse. As a result of the heat capacity of small transistors, general fuse protection in general can not play a role in the rapid fuse common fuse. This method has the advantage of the protection of vulnerable, but it needs to switch transistor in accordance with specific security requirements of the work area to select the fuse specifications. This disadvantage is over-current protection measures brought about by the inconvenience of frequent replacement of fuses.Linear voltage regulator commonly used in the protection and currentlimiting to protect the cut-off in the switching regulator can be applied. However, according to the characteristics of switching regulators, the protection circuit can not directly control the output transistor switches, and over current protection must be converted to pulse output commands to control the modulator to protect the transistor switch. In order to achieve over-current protection are generally required sampling resistor in series in the circuit, this will affect the efficiency of power supply, so more for low-power switching regulator of occasions. In the high-power switching power supply, by taking into account the power consumption should be avoided as far as possible access to the sampling resistor. Therefore, there will usually be converted to over-current protection, and under-voltage protection.E、Over-voltage protectionSwitching regulator's input over-voltage protection, including over-voltage protection and output over-voltage protection. Switching regulator is not used in DC power supply voltage regulator and rectifier, such as battery voltage, if too high, so switching regulator is not working properly, or even damage to internal devices, therefore, it is necessary to use the input over-voltage protection circuit. Using transistors and relays protection circuit.In the circuit, when the input DC power supply voltage higher than the voltage regulator diode breakdown voltage value, the breakdown voltage regulator tube, a current flowing through resistor R, so that V turn-on transistor, relay, normally closed contact off open, cut off the input. Voltage regulator voltage regulator which controls the value of Vs. = Earwax-UBE. The polarity of input power with the input protection circuit can be combined with over-voltage protection, polarity protection constitute a differential circuit and over voltage protection.Output over-voltage protection switching power supply is essential. In particular, for the 5V output of the switching regulator, it is a lot of load on a high level of integration of the logic device. If at work, switching regulator sudden damage to the switch transistor, the output potential may be increased immediately to the importation of non-regulated DC power supply voltage value, causing great loss instantaneous. Commonly used method is short-circuit protection thirsted. The simplest over-voltage protection circuit. When the output voltage is too high, the regulator tube breakdown triggered thirstier turn-on, the output short-circuit, resulting in over-current through the fuse or circuit protective device to cut off the input to protect the load. This circuit is equivalent to the response time of the opening time of thirstier is about 5 ~ 10μs. The disadvantage is that its action is fixed voltage, temperature coefficient, and action points of instability. In addition, there is a voltage regulator control parameters of the discrete, model over-voltage start-up the same but has different values, difficult to debug. Esc a sudden increase in output voltage, transistors V1, V2 conduction, the thruster conduction. Reference voltage Vs. by type.F、Under-voltage protectionOutput voltage below the value to reflect the input DC power supply, switching regulator output load internal or unusual occurrence. Input DC power supply voltage drops below the specified value would result in switching regulator output voltage drops, the input current increases, not only endanger the switching transistor, but also endanger the input power. Therefore, in order to set up due to voltage protection. Due to simple voltage protection.When no voltage regulator input normal, ZD breakdown voltage regulator tube, transistors V conduction, the relay action, contact pull-in, power-switching regulator. When the input below the minimum allowable voltage value, the regulator tube ZD barrier, V cut-off, contact Kai-hop,switching regulator can not work. Internal switching regulator, as the control switch transistor circuit disorders or failure will decrease the output voltage; load short-circuit output voltage will also decline.Especially in the reversed-phase step-up or step-up switching regulator DC voltage of the protection due to over-current protection with closely related and therefore more important. Implementation of Switching Regulators in the termination of the output voltage comparators.Normally, there is no comparator output, once the voltage drops below the allowable value in the comparator on the flip, drive alarm circuit; also fed back to the switching regulator control circuit, so that switching transistor cut-off or cut off the input power.G、Over-temperature protectionSwitching regulator and the high level of integration of light-weight small volume, with its unit volume greatly increased the power density, power supply components to its work within the requirements of the ambient temperature is also a corresponding increase. Otherwise, the circuit performance will deteriorate premature component failure. Therefore, in high-power switching regulator should be set up over-temperature protection.Relays used to detect the temperature inside the power supply temperature, when the internally generated power supply overheating, the temperature of the relay on the action, so that whole circuit in a warning alarm, and the realization of the power supply over-temperature protection. Temperature relay can be placed in the vicinity of the switching transistor, the general high-power tube shell to allow the maximum temperature is 75 ℃, adjust the temperature setting to 60 ℃. When the shell after the temperature exceeds the allowable value to cut off electrical relay on the switch protection. Semiconductor switching device thermal "hot thirstier," in the over-temperature protection, played an important role. It can be used asdirected circuit temperature. Under the control of p-hot-gate thirstier (TT102) characteristics, by RT value to determine the temperature of the device turn-on, RT greater the temperature the lower the turn-on. When placed near the power switching transistor or power device, it will be able to play the role of temperature instructions. When the power control the temperature of the shell or the internal device temperature exceeds the allowed value, the heat conduction thirstier on, so that LED warning light. If the opt coupler with, would enable the whole circuit alarm action to protect the switching regulator. It can also be used as a power transistor as the over-temperature protection, crystal switch the base current by n-type gate control thirstier TT201 thermal bypass, cut-off switch to cut off the collector current to prevent overheating.H、The future development of relay protectionProtection technology to future trends is computerized, network, intelligent, protection and control, measurement and data communications integration development.1) ComputerizedAlong with the rapid development of computer hardware, microcomputer protection and development in hardware. Former north electricity institute of computer line protection hardware has experienced three development stages: from eight single CPU structure of the microcomputer relay protection, less than 5 years time to develop more CPU structure, and to develop the large don't bus module, performance greatly improve module structure, widely used. Huazhong university of science and technology development of microcomputer protection from 8 bits CPU, is the core part in polymerizing-kettle development based on 32-bit microcomputer protection.Nanjing institute of electrical automation began a 16-bit CPU is developed on the basis of computer line protection, has been widespread inthe study, also protect the hardware system 32 bits. The development of southeast university computer hardware and equipment to protect and improve through a lot. Tianjin university is a start with more than 16 bits CPU developed on the basis of computer line protection, which began in 1988 study 32-bit digital signal processor (DSP) for the protection and control, measuring devices, microcomputer integrated with Zhuhai jin electrical automation equipment company developed into a fully functional 32-bit big modules, a module is a small computer. Using 32-bit microcomputer chip is not only because the accuracy and precision of the A/D converter by the resolution limit, more than 16 when converting speed and cost is unacceptable, More important is the 32-bit microcomputer chip with high integrity, high frequency and computing speed and large space, rich addressing the command system and more input output. The CPU registers, data bus, the address bus are 32-bit memory management function, and memory protection function and tasks, and the conversion function will Cache (Cache) and floating-point components are integrated in the CPU.2）NetworkPower system of microcomputer protection requirement, besides improving the basic function of protection, also should have the capacity of the fault information and data storage space, long-term fast data processing function, strong communication ability, and other protection and control devices and the whole system by sharing network dispatching data, information and network resources, the ability to program in a high-level language, etc. This requires microcomputer protection device is equivalent to a PC. In the early development of computer to protect, once thought to use a small computer finish relay protection device. Due to the large size, then minicomputers high cost and reliability of this idea is not reality. Now, with microprocessor-based protection function of similar size, speed, work-managing machine greatly exceed the storage capacity ofminicomputer, therefore, make use of the relay protection sets polymerizing-kettle time is ripe, this is the development direction of the microcomputer relay protection.Tianjin University has developed with microprocessor-based protection device with an identical structure reform polymerizing-kettle of relay protection device. This device has several advantages: (1) 486PC machine can meet all the functions of the current and future demands of microcomputer protection function. (2) dimension and structure and the current protection device, exquisite workmanship, shockproof, prevent overheating, preventing electromagnetic interference ability is strong, can run in very bad working environment, cost can be accepted. (3) using STD bus or PC bus, hardware modular, for different protection can be arbitrarily choose different modules, flexible configuration, easy extension.The microcomputer relay protection device, computerized is irreversible trend. But how to better satisfy power system, how to further improve the reliability of the relay protection, and how to obtain more economic benefit and social benefit, still must specifically in-depth research. 820 networksThe computer network information and data communication tool has become the mainstay of the information age, make human production technology and social life of the fundamental changes have taken place. It is deeply affect all industries, as well as various industry provides powerful means of communication. So far, in addition to the differential protection disoperation and protection of the relay protection device, all can only protect the electricity installation reaction. Protection function is limited, reduce accidents resection fault components. This is mainly due to the lack of data communications. Strong Foreign had put forward the concept of protection system, which was mainly refers to the safety automatic device. Because of the relay protection function not only fault components and limitresection impact accident (this is to ensure priority), the safe and stable operation of the whole system. This requires each protection unit can be altogetherI、ConclusionDiscussed above in the switching regulator of a variety of conservation, and introduces a number of specific ways to achieve. Of a given switching power supply is concerned, but also protection from the whole to consider the following points:1) The switching regulator used in the switching transistor in the DC security restrictions on the work of regional work. The transistor switches selected by the manual available transistors get DC safe working area. According to the maximum collector current to determine the input value of over-current protection. However, the instantaneous maximum value should be converted to the average current. At rated output current and output voltage conditions, the switch of the dynamic load line does not exceed a safe working area DC maximum input voltage, input over-voltage protection is the voltage value.2)The switching regulator output limit given by the technical indicators within. Work within the required temperature range, the switching regulator's output voltage, the lower limit of the output is off, due to the voltage value of voltage protection. Over-current protection can be based on the maximum output current to determine. False alarm in order not to protect the value of a certain margin to remain appropriate.3)From the above two methods to determine the protection after the power supply device in accordance with the needs of measures to determine the alarm. Measures the general alarm sound and light alarm two police. Voice of the police applied to more complex machines, power supply parts and do not stand out in a place, it can give staff an effective warning of failure; optical Police instructions can be eye-catching and fault alarm andpointed out that the fault location and type. Protection measures should be protected as to determine the location. In the high-power, multi-channel power supply, always paying, DC circuit breakers, relays, etc. high-sensitivity auto-protection measures, to cut off the input power supply to stop working the system from damage. Through the logic control circuit to make the appropriate program cut-off switch transistor is sensitive it is convenient and economic. This eliminated large, long response time, the price of your high-power relay or circuit breaker.4) The power of putting in the protection circuit will be affected after the reliability of the system, for which want to protect the reliability of the circuit itself is higher in order to improve the reliability of the entire power system, thereby increasing its own power supply MTBF. This requires the protection of strict logic, the circuit is simple, at least components, In addition to the protection circuit should also be considered a failure of maintenance of their difficulty and their power to protect the damage.Therefore, we must be comprehensive and systematic consideration of a variety of switching power supply protection measures to ensure the normal operation of switching power supplies and high-efficiency and high reliability.直流开关稳压电源的保护技术摘要：讨论了直流开关稳压电源的保护系统,提出保护系统设计的原则和整机保护的措施，分析了开关稳压电源中的各种保护的特点及其设计方法,介绍了几种实用保护电路。

武汉轻工大学毕业设计（论文）外文参考文献译文本2014届原文出处DC Switching Power Supply Protection Technology毕业设计(论文)题目基于C51的模拟交通灯控制系统设计（硬件部分）院（系）电气与电子工程学院专业名称自动化学生姓名周玉学生学号100408322指导教师秦岭直流开关电源的保护技术摘要：讨论直流开关电源保护系统、保护系统的设计原则和机器保护措施,分析开关电源的保护的特点及其设计方法,介绍一些实用的保护电路。
关键字：开关电源保护电路系统设计一、引言直流开关稳压器使用的大功率开关器件价格昂贵,控制电路比较复杂；另外,开关稳压器的负载都是用大量的集成化程度很高的器件安装的电子系统。
晶体管和集成器件耐受电、热冲击的能力较差。
因而开关稳压器的保护应该兼顾稳压器本身和负载的安全。
保护电路的种类很多,这里介绍极性保护、程序保护、过电流保护、过电压保护、欠电压保护以及过热保护等电路。
通常选用几种保护方式组合,构成完善的保护系统。
二、极性保护直流开关稳压器的输入一般都是未稳压直流电源。
由于操作失误或者意外情况会将其极性接错,将损坏开关电源。
极性保护的目的,就是使开关稳压器仅当以正确的极性接上未稳压直流电源时才能工作。
利用单向导通的器件可以实现电源的极性保护。
由于二极管D要流过开关稳压器的输入总电流,因此这种电路应用在小功率的开关稳压器上比较合适。
在较大功率的场合,则把极性保护电路作为程序保护中的一个环节,可以省去极性保护所需的大功率二极管,功耗也将减小。
为了操作方便,便于识别极性正确与否,在二极管之后接指示灯。
三、程序保护开关稳压电源的电路比较复杂,可以分为小功率控制部分和大功率开关部分。
开关晶体管则属大功率，为保护开关晶体管在开启或关断电源时的安全,必须先让调制器、放大器等小功率的控制电路工作。
因此,要保证正确的开机程序。
开关稳压器的输入端一般接有小电感、大电容的输入滤波器。
在开机瞬间,滤波电容器会流过很大的浪涌电流,这个浪涌电流可以为正常输入电流的数倍。
这样大的浪涌电流会使普通电源开关的触点或继电器的触点熔化,并使输入保险丝熔断。
另外,浪涌电流也会损害电容器,使其寿命缩短。
因此,开机时应该接入一个限流电阻,通过这个限流电阻来对电容器充电。
为了不使该限流电阻消耗过多的功率，以至于影响开关稳压器的正常工作,而在开机暂态过程结束后，用一个继电器自动短接它,使直流电源直接对开关稳压器供电。
这种电路称为开关稳压器的“软启动”电路。
开关稳压器的控制电路中的逻辑组件或者运算放大器需用辅助电源供电。
为此,辅助电源必须先于开关电路工作。
这可用开机程序控制电路来保证。
一般的开机程序是:输入电源的极性鉴别,电压保护→开机程序电路工作→辅助电源工作并通过限流电阻 R对开关稳压器的输入电容器C充电→开关稳压器的调制电路工作，短路限流电阻→开关稳压器稳定工作。
在开关稳压器中,刚开机时,因为其输出电容容量大,充到额定输出电压值需要一定时间。
在这段时间内,取样放大器输入低的输出电压采样,根据系统闭环调节特性将迫使开关三极管的导通时间加长,这样一来,开关三极管就会在这段期间内趋于连续导通,而容易损坏。
为此,要求在开机这一段时间内,开关调制电路输出给开关三极管基极的脉宽调制驱动信号，能保证开关三极管由截止逐渐趋于正常的开关状态，故而要加设开机保护以配合软启动。
四、过电流保护当出现负载短路、过载或者控制电路失效等意外情况时,会引起流过稳压器中开关三极管的电流过大，使管子功耗增大,发热,若没有过流保护装置,大功率开关三极管就有可能损坏。
故而在开关稳压器中过电流保护是常用的。
最经济简便的方法是用保险丝。
由于晶体管的热容量小,普通保险丝一般不能起到保护作用,常用的是快速熔断保险丝。
这种方法具有保护容易的优点，但是,需要根据具体开关三极管的安全工作区要求来选择保险丝的规格。
这种过流保护措施的缺点是带来经常更换保险丝的不便。
在线性稳压器中常用的限流保护和电流截止保护在开关稳压器中均能应用。
但是,根据开关稳压器的特点,这种保护电路的输出不能直接控制开关三极管,而必须使过电流保护的输出转换为脉冲指令,去控制调制器以保护开关三极管。
为了实现过电流保护一般均需要用取样电阻串联在电路中,这会影响电源的效率,因此多用于小功率开关稳压器的场合。
而在大功率的开关稳压电源中,考虑到功耗，应尽量避免取样电阻的接入。
因此,通常将过电流保护转换为过、欠电压保护。
五、过电压保护开关稳压器的过电压保护包括输入过电压保护和输出过电压保护。
开关稳压器所使用的未稳压直流电源诸如蓄电池和整流器的电压如果过高,使开关稳压器不能正常工作,甚至损坏内部器件,因此,有必要使用输入过电压保护电路。
在该电路中，当输入直流电源的电压高于稳压二极管的击穿电压值时，稳压管击穿，有电流流过电阻R，使晶体管V导通，继电器动作，常闭接点断开，切断输入。
其中稳压管的稳压值Vs. = Earwax-UB E。
输入电源的极性保护电路可以跟输入过电压保护结合在一起,构成极性保护鉴别与过电压保护电路。
输出过电压保护在开关稳压电源中是至关重要的。
特别对输出为5V的开关稳压器来说,它的负载是大量的高集成度的逻辑器件。
如果在工作时,开关稳压器的开关三极管突然损坏,输出电位就可能立即升高到输入未稳压直流电源的电压值,瞬时造成很大的损失。
常用的方法是晶闸管短路保护。
当输出电压过高时,稳压管被击穿,触发晶闸管导通,把输出端短路,造成过电流,通过保险丝或电路保护器将输入切断,保护了负载。
这种电路的响应时间相当于晶闸管的开通时间，约为5～10μs。
它的缺点是动作电压是固定的，温度系数大，动作点不稳定。
另外，稳压管存在着参数的离散性，型号相同但过电压起动值却各不相同，给调试带来了困难。
六、欠电压保护输出电压低于规定值时，反映了输入直流电源、开关稳压器内部或者输出负载发生了异常。
输入直流电源电压下降到规定值之下时，会导致开关稳压器的输出电压跌落，输入电流增大，既危及开关三极管，也危及输入电源。
因此，要设欠电压保护。
当未稳压输入的电压值正常时，稳压管ZD击穿，晶体管V导通，继电器动作，触点吸合，开关稳压器加电。
当输入低于所允许的最低电压值时，稳压管ZD不通，V截止，触点跳开，开关稳压器不能工作。
开关稳压器内部，由于控制电路失常或者开关三极管失效会使输出电压下降；负载发生短路也会使输出电压下降。
特别在升压型或反相升压型的直流开关稳压器中欠电压的保护是跟过电流保护紧密相关的，因而更加重要。
实现方法是在开关稳压器的输出端接电压比较器。
正常时，比较器没有输出，一旦电压跌落在允许值之下比较器就翻转，驱动告警电路;同时反馈到开关稳压器的控制电路，使开关三极管截止或切断输入电源。
七、过热保护开关稳压器的高集成化和轻量小体积，使其单位体积内的功率密度大大提高，电源装置内部的元器件对其工作环境温度的要求也相应提高。
否则，会使电路性能变坏，元器件过早失效。
因此在大功率开关稳压器中应该设过热保护。
采用温度继电器来检测电源装置内部的温度，当电源装置内部产生过热时，温度继电器就动作，使整机告警电路处于告警状态，实现对电源的过热保护。
亦可将温度继电器置于开关三极管的附近，一般大功率管允许的最高管壳温度是75℃，调节温度整定值为60℃。
当管壳温度超过允许值后继电器就切断电器，对开关管进行保护。
半导体热敏开关器件“热晶闸管”在超温保护方面有重要作用。
它可以用作温度指示电路。
根据p型控制栅热晶闸管(TT102)的特性，由RT值确定该器件的导通温度，RT越大，导通温度越低。
当将其放置功率开关三极管附近，或在电源装置内时，它就能起到温度指示作用。
当功率管的管壳温度或者装置内部的温度超过允许值时，热晶闸管就导通，使发光二极管发亮告警。
倘若配合光电耦合器，就可使整机告警电路动作，保护开关稳压器。
它亦可以用作功率晶体管的过热保护，晶体开关管的基极电流被n 控制栅型热晶闸管TT201旁路，开关管截止，切断集电极电流,防止过热。
八、继电保护的未来发展继电保护技术未来趋势是向计算机化，网络化，智能化，保护、控制、测量和数据通信一体化发展。
1）计算机化随着计算机硬件的迅猛发展，微机保护硬件也在不断发展。
原华北电力学院研制的微机线路保护硬件已经历了3个发展阶段：从8位单CPU结构的微机保护问世，不到5年时间就发展到多CPU结构，后又发展到总线不出模块的大模块结构，性能大大提高，得到了广泛应用。
华中理工大学研制的微机保护也是从8位CPU，发展到以工控机核心部分为基础的32位微机保护。
南京电力自动化研究院一开始就研制了16位CPU为基础的微机线路保护，已得到大面积推广，目前也在研究32位保护硬件系统。
东南大学研制的微机主设备保护的硬件也经过了多次改进和提高。
天津大学一开始即研制以16位多CPU 为基础的微机线路保护，1988年即开始研究以32位数字信号处理器(DSP)为基础的保护、控制、测量一体化微机装置，目前已与珠海晋电自动化设备公司合作研制成一种功能齐全的32位大模块，一个模块就是一个小型计算机。
采用32位微机芯片并非只着眼于精度，因为精度受A/D转换器分辨率的限制，超过16位时在转换速度和成本方面都是难以接受的；更重要的是32位微机芯片具有很高的集成度，很高的工作频率和计算速度，很大的寻址空间，丰富的指令系统和较多的输入输出口。
CPU的寄存器、数据总线、地址总线都是32位的，具有存储器管理功能、存储器保护功能和任务转换功能，并将高速缓存(Cache)和浮点数部件都集成在CPU内。
2）网络化电力系统对微机保护的要求不断提高，除了保护的基本功能外，还应具有大容量故障信息和数据的长期存放空间，快速的数据处理功能，强大的通信能力，与其它保护、控制装置和调度联网以共享全系统数据、信息和网络资源的能力，高级语言编程等。
这就要求微机保护装置具有相当于一台PC机的功能。
在计算机保护发展初期，曾设想过用一台小型计算机作成继电保护装置。
由于当时小型机体积大、成本高、可靠性差，这个设想是不现实的。
现在，同微机保护装置大小相似的工控机的功能、速度、存储容量大大超过了当年的小型机，因此，用成套工控机作成继电保护的时机已经成熟，这将是微机保护的发展方向之一。
天津大学已研制成用同微机保护装置结构完全相同的一种工控机加以改造作成的继电保护装置。
这种装置的优点有：(1)具有486PC机的全部功能，能满足对当前和未来微机保护的各种功能要求。
(2)尺寸和结构与目前的微机保护装置相似，工艺精良、防震、防过热、防电磁干扰能力强，可运行于非常恶劣的工作环境，成本可接受。
(3)采用STD总线或PC总线，硬件模块化，对于不同的保护可任意选用不同模块，配置灵活、容易扩展。
