电脑开关电源维修图
电脑开关电源维修图解电脑开关电源维修图解一颗强劲的CPU可以带着我们在复杂的数码世界里飞速狂奔，一块最酷的显示卡会带着我们在绚丽的3D世界里领略那五光十色的震撼，一块最棒的声卡更能带领我们进入那美妙的音乐殿堂。
相对于CPU，显示卡、声卡而言，电源可能是微不足道的，我们对它的了解也不是很多，可是我们必须知道，一个稳定工作的电源，是使我们计算机能够更好工作的前提。
计算机开关电源工作电压较高，通过的电流较大，又工作在有自感电动势的状态下，因此，使用过程中故障率较高。
对于电源产生的故障，不少朋友束手无策，其实，只要有一点电子电路知识，就可以轻松的维修电源。
首先，我们要知道计算机开关电源的工作原理。
电源先将高电压交流电（220V）通过全桥二极管（图1、2）整流以后成为高电压的脉冲直流电，再经过电容滤波（图3）以后成为高压直流电。
此时，控制电路控制大功率开关三极管将高压直流电按照一定的高频频率分批送到高频变压器的初级（图4）。
接着，把从次级线圈输出的降压后的高频低压交流电通过整流滤波转换为能使电脑工作的低电压强电流的直流电。
其中，控制电路是必不可少的部分。
它能有效的监控输出端的电压值，并向功率开关三极管发出信号控制电压上下调整的幅度。
在计算机开关电源中，由于电源输入部分工作在高电压、大电流的状态下，故障率最高；其次输出直流部分的整流二极管、保护二极管、大功率开关三极管较易损坏；再就是脉宽调制器TL494的4脚电压是保护电路的关键测试点。
通过对多台电源的维修，总结出了对付电源常见故障的方法。
一、在断电情况下，“望、闻、问、切”由于检修电源要接触到220V高压电，人体一旦接触36V以上的电压就有生命危险。
因此，在有可能的条件下，尽量先检查一下在断电状态下有无明显的短路、元器件损坏故障。
首先，打开电源的外壳，检查保险丝（图5）是否熔断，再观察电源的内部情况，如果发现电源的PCB板上元件破裂，则应重点检查此元件，一般来讲这是出现故障的主要原因；闻一下电源内部是否有糊味，检查是否有烧焦的元器件；问一下电源损坏的经过，是否对电源进行违规的操作，这一点对于维修任何设备都是必须的。

说起开关电源，相信我们都不陌生，那开关电源有时候在使用中也会或多或少的出现一些小问题或者故障，那就需要我们及时检测出故障，并且进行开关电源维修。
虽然开关电源电路有易有难，功率有大有小，输出电压多种多样，但是按照店铺总结的以下内容，应该可以达到事半功倍的效果。
开关电源维修共有以下六个步骤：开关电源维修步骤1、修理开关电源时，首先用万用表检测各功率部件是否击穿短路，如电源整流桥堆，开关管，高频大功率整流管;抑制浪涌电流的大功率电阻是否烧断。
再检测各输出电压端口电阻是否异常，上述部件如有损坏则需更换。
开关电源维修步骤2、第一步完成后，接通电源后还不能正常工作，接着要检测功率因数模块(PFC)和脉宽调制组件(PWM)，查阅相关资料，熟悉PFC和PWM模块每个脚的功能及其模块正常工作的必备条件开关电源维修步骤开关电源维修步骤。
开关电源维修步骤3、然后，对于具有PFC电路的电源则需测量滤波电容两端电压是否为380VDC左右，如有380VDC左右电压，说明PFC模块工作正常，接着检测PWM组件的工作状态，测量其电源输入端VC，参考电压输出端VR，启动控制Vstart/Vcontrol端电压是否正常，利用220VAC/220VAC隔离变压器给开关电源供电，用示波器观测PWM模块CT端对地的波形是否为线性良好的锯齿波或三角形，如TL494CT端为锯齿波，FA5310其CT端为三角波。
输出端V0的波形是否为有序的窄脉冲信号。
开关电源维修步骤4、在开关电源维修实践中，有许多开关电源采用UC38××系列8脚PWM组件，大多数电源不能工作都是因为电源启动电阻损坏，或芯片性能下降。
当R断路后无VC，PWM组件无法工作，需更换与原来功率阻值相同的电阻。
Lynergy电源电热器操作与维护手册说明书
Installation, Operation & Maintenance Manual forthe Lynergy Electric Heat with Discharge Temperature LimitContentsPageIntroduction ............................................................. 1 General .................................................................... 1 Inspection ................................................................ 1 Preparation .............................................................. 1 Operation ................................................................. 2 Troubleshooting .. (4)IntroductionLynergy is a patented (USPN 7,177534) electronic, time proportional electric heat system. The heat output of the heater is modulated utilizing quiet, rapid performing solid state relays. The relays are switched off and on to allow the heating of electrical resistance elements. Theproportion of time the relay is on dictates the proportion of maximum heat the electric heater can produce. The solid state relays are switched off and on by a supplied Electric Heat Module (EHM). The EHM accepts an input signal from the terminal unit controller or thermostat for theamount of heat desired. The EHM can accept a variety of different input signals when interfacing with controls. The type of input the EHM will accept is modified by changing the position of one to three jumpers easily accessible on the board.The Lynergy is available with an optional dischargetemperature sensor. When used with the discharge sensor option, the Lynergy will modulate outgoing temperature from the unit between the maximum temperature setting and initial temperature of incoming air before heating began. The discharge temperature set point is easilyadjusted in the field by rotating the temperature dial on the EHM. The EHM will not allow temperatures over the set point so as to prevent overheating, stratification, and energy waste from heated air lost through overhead returns.Additional information may be found at the Titus website, .GeneralThe following information is to be used by the installer as a guide. Since each installation is unique unto itself, only general topics are covered. Topic order may not be the same as required by actual installation.This guide is not intended to supersede or circumvent any applicable national, state or local codes.The installation is to be performed only by individuals whose experience meets or exceeds the requirements of the work involved.The installer MUST read the entire contents of this guide and develop a thorough understanding before beginning installation.Due to a continuing program of product research,Titus reserves the right to discontinue or change without notice, any or all specifications or designs without incurring obligations.InspectionThoroughly inspect all packages upon receipt. Ensure carton(s) have not been dropped, crushed or punctured. Inspect all contents for damage. If damage is found, immediately file a claim with the delivering carrier.PreparationUnpack Lynergy and check contents against the Bill of Materials.Review all submittal drawings and verify that all components have been delivered.Store all components in a clean and secure area.OperationInput SettingThe Lynergy board is capable of being controlled and operated 10 different ways. The units are ordered with an LXY code, where “X” is coded for unit power and “Y” is coded for the application. This “Y” application can be changed in the field. The application desired is chosen by placement of jumpers in the corner of board. Jumper settings below are representative of pins at bottom right of control board as shown in drawing. Wiring diagrams for each are on pages 6 & 7.On/Off: This application accepts one 24 Vacinput at Out 1 to step the heater output fromOFF to 100% heater kW rating. The signalmay be pulsed off and on over a small timeperiod to provide proportional heat. Forexample, a signal that is on for 4.5 secondsevery 10 seconds would produce 45% of theheater’s kW rating. This is the default value forLX1 heat.2 Stage (2Stg): This two stage applicationaccepts two 24 Vac inputs to step the heateroutput from off to 50% or 100% heater kWrating. This is the default value for LX2 heat.0-10V: This application accepts a 0-10 Vdc (0-20mA) signal to modulate the heater output.The output is proportional to input signal (i.e.,4.5 volts sets the heater to 45% of kW rating).This is the default value for LX3 heat.2-10V: This application accepts a 2-10 Vdc (4-20 mA) signal to modulate the heater output.The output is proportional to input voltageabove 2 volts (i.e., 4.5 volts sets the heater to25% of kW rating). This is the default value forLX4 heat.3 Point Floating (FLT2): This floating inputapplication accepts two 24 Vac inputs toincrease or decrease the heater output. Aseither an increase or decrease signal is sent,the heater output will change at a rate of 1%per second. When no change is called, theheater output remains constant at the value ofthe last call. This is the default value for LX7heat.Thermostat (Incr): This application acceptsone 24 Vac input to modulate heater output.An output signal will increase the heater output1% per second. When the output is off, heatdecreases at a rate of 1% per second. This isthe default value for LX5 heat.Binary (B2): This application accepts two 24Vac inputs to step the heater from off to 33%,67%, or 100% of the heater’s kW rating. Thisis the default value for LX6 heat.WiringThe EHM control board is powered by 24Vac (1) from thetransformer in the electric heater. The EHM has auxiliary24Vac outputs (2) that can be used to power the unit’selectrical controls. Next to the “Xfmr” inputs are the “+” and“-“ Relay connections (3) that control the solid state relaysby sending pulses of ~25Vdc.There are two terminations to use for dc Volt control (4) ofthe electric heat (applications LX3 and LX4 from above).These are polar sensitive. The “+” signal from the controllermust be connected to “Signal” on the EHM Control Board.The “-“ from the controller must be connected to “Com” nextto “Signal (Note: NOT “iCom”). A termination to “-“ ispossible, but not necessary to measure mA signals to theboard.There are three terminations for 24 Vac control (5) of theelectric heat (applications LX1, LX2, LX5, LX6, and LX7from above). “Inc” is for the increase signal in applicationsLX5 and LX7, as well as the first stage heat signal inapplications LX1, LX2, and LX6. “Dec” is for the decreasesignal in application LX7, as well as the second stage heatsignal in applications LX2 and LX6. A connection to “iCom”is necessary for all of these 24 Vac applications. If theunit’s controller does not have a Common output, a jumperto the correct “Aux” terminal can be used. If the unitcontroller outputs the “24Vac” side from it’s input power, ajumper should be made from “Neutral” to “iCom” (Seesample diagram on page 7). If the unit controller outputsthe “Neutral” side of it’s input power, a jumper should bemade from “24Vac” to “iCom”.Discharge Temperature Set PointLynergy comes with a discharge temperature set point (DTS) option. This option allows a maximum temperature to be set at the board to prevent overheating of discharge air. When the unit receives a signal to start heating, the board will take an initial temperature reading and modulate heat from that point to the maximum temperature. For example, if a thermostat requires only a 10% heating output of air that was initially 60°F and has a maximum temperature setting of 90°F, the EHM will modulate the heater’s output temperature to 63°F (the additional 3 degrees coming from (90-60)*10%). This allows heaters to be sized for morning warm up in the winter and still comfortably operate on those days when the inlet temperatures are slightly warmer.The discharge temperature sensor comes with a 9’ cable for mounting in the downstream ductwork. The sensor should be mounted a minimum of 36” from the discharge of the unit and be vertically centered in the ductwork. The sensor can be mounted by drilling a 1/2” hole into the ductwork, inserting the sensor, and securing it with 2 sheet metal screws. The sensor is 6” long, and the tip should not touch any part of the ductwork.Neither the jumper settings nor the controls wiring needs to be changed when this option is ordered. The EHM control board will detect if a sensor has been connected, and it will adjust the control function accordingly. The sensor wires areconnected to the screw terminals at the “Sensor” (6) location on the EHM. The connection at this termination is not polar sensitive and the two wires may be switched with no effect. The desired discharge temperature is set by rotating the discharge temperature set point dial arrow to the maximum outlet temperature desired. To fine tune the dischargetemperature set point, connect the positive and negative leads of a multi-meter to “Tcal” and “Com” (7), respectively, on the EHM. Then place a jumper between the two screw heads on the sensor termination. Rotate the discharge temperature set point dial until the desired voltage per temperature isobtained. After the voltage is obtained, the EHM board must be reset. To reset the board, remove the jumpers and then place back in correct position.TroubleshootingProblem: No heat when called for1. Confirm the jumper setting is correct for the input given.2. If the controls are outputting Vdc, the jumper should be set as shown on page 2 for applications LX3, and LX4.3. If the controls are outputting 24Vac, the jumper setting should be set as shown on page 2 for applications LX1, LX2,LX5, LX6, & LX7. (Also see diagrams on page 6 & 7)4. Check that wiring to the EHM is correct.5. If using applications LX3 and LX4, confirm the positive Vdc connection is wired to the “Signal” terminal, and thenegative Vdc connection is wired to the “Com“ terminal.6. If using 24Vac, confirm the wires are terminated correctly at (5) with a connection at “iCom”. If an “Aux” terminal (2) onthe EHM has been jumpered to “iCom”, make sure that the opposite 24Vac input is what is outputted at the controls.7. Check that airflow is above minimum. Terminal units with electric heat come with pressure switches to insure thatheater elements have airflow over them. See catalog for minimum airflow required for specific size terminal units. Fan boxes must have minimum downstream static of 0.2”8. Check that discharge temperature setpoint is not below the airflow temperature.9. Check Relay wiring. Solid state relays are polarity sensitive. The wire from “+” on the EHM control board should beterminated on “+3” VDC terminal of the relay. The wire from “-“ on the EHM control board should be terminated on “4-“ VDC terminal of the relay. If there are two relays used in the heater, the relays are daisy chained from “4-“ to “+3”together.10. Check the potentiometer on the SSR control board to ensure that it is in the 100% position.Problem: Discharge Temperature not at Temperature Setting1. Check that wires from sensor are stripped and terminated in EHM control terminals.2. Check that wires from controls are terminated at the correct point on EHM board. Increase or stage 1 signal should beterminated at “Inc”. Decrease or stage 2 signal should be terminated at “Dec”.3. Check volt setting.4. Check sensor placement. Make sure that sensor is well placed vertically in ductwork and at least 36” from discharge.Sensor tip should not touch inside of ductwork.5. Try staging or ramping of output on oversized heaters. When controls call for full heat from cooling mode, if heatersare too large and heating times are small, the heater output may be over setpoint. Staging or ramping of output over a60 second interval will provide smooth transition. If only one output of heat is available from controls, application LX5will proportionally ramp heat output frm 0 to 100% over a 2 minute 1 second span.。

IPS 功能框图配电配电包括供电到整流器的交流输入配电及从整流器到负载或电池的直流输出配电。
在IPS 中，有两个模块控制配电（打开带锁的门或直接在面板上就可以操作）：1．交流配电模块交流配电模块给整流器提供交流输入电源。
一个安装在交流输入上的空气开关，能使IPS 与交流输入电源隔离。
小型空气开关（MCB ）保护连接各整流器的配电电缆，以防短路和过载，并且能隔离每台整流器。
在交流配电模块内装有防止电压冲击和浪涌的保护装置。
如果浪涌保护装置有故障，便有告警信号传给SM50。
2．直流配电模块直流配电模块将直流电源从整流器输送到负载和电池。
直流配电模块有两种类型：微型电路开关型（DCM）和熔断器型（DCF）。
DCM和DCF两者都是可用于隔离各负载和电池的电缆，并且保护他们以防过载。
如根据需要，低压脱离（LVD）模块可以安装在DCM模块中。
3．低压脱离模块（LVD）当长时间交流电故障，LVD模块保护电池，以防电池过放电。
当电池电压降到低于预设值时，LVD模块使用一个电磁离合器断开电池。
当电压升到高于预设值时，LVD模块重接电池。
可以将LVD连接成一个电池或负载的断路装置。
LVD模块可以在SM50的控制下自动运行，也可通过SM50前面板或直接在LVD模块上手动重接。
在操作过程中，LVD模块接收SM50发来的控制信号，并将其状态信号送回给SM50。
4．整流器器将交流电输入转换为直流电输出，向电池和负载供电。
交流输入是从外部交流供电通过交流配电模块获得。
每台整流器的输出都连接到汇流排上，并通过直流配电模块配电。
在整流器内部有一个微处理器，用来监视整流器状况及控制整流器输出参数。
整流器通过RS-485串行口连接到SM50上。
SM50发送命令给整流微处理器来改变整流器的操作参数。
当被查询时，微处理器将整流器信息送给SM50。
整流器安装在系统的整流器架中。
从IPS的正面将整流器插入整流器架背板的连接插座上。
每个整流器架可安插三台整流器。
整流器告警及运行状态均由前面板LED显示。
5．监控模块SM50监控模块监控IPS的运行，发布命令控制整流器及LVD的运行。
每个模块都被监视，一旦发生影响系统性能的故障，便触发告警器。
监控模块接收电流、电压和温度感应器的模拟量输入。
有六个用户配置数字输入和从IPS各模块来的数字输入，还有一个RS-232C串行口用来配置监控模块运行参数。
监控模块有十个继电器输出。
它们通常用于操作外部告警器。
两个附加的继电器输出用来控制LVD模块。
通过RS-485串行口与整流器之间传送控制命令和数据。
