一、问题描述

灯带在测试感应雷浪涌时极易损坏功率开关，为此我们需要对灯带的抗浪涌能力进行加强，原电路是有一个压敏电阻进行保护，估计是残压太高了，导致功率开关损坏，下面就进行整改。

二、测试要求

浪涌：差模2kV，测试次数±5次。

三、浪涌介绍

我们参考的浪涌标准是国标；国标、GB/T 17626.5——2019对标国际标准IEC61000-4-5：2014，这是目前最新的标准。

浪涌细分的话种类是挺多的，这里测试的是8/20μs-1.2/50μs的组合波形，8/20μs是电流波，1.2/50μs是电流波，它们的内阻是2Ω。波形图如下；

浪涌电压从零开始到几百kV，而我们现在使用的是属于感应雷部分，感应雷部分也有他的电压等级分类，下面是他的等级表格，如下图；

试验等级

测试一般模拟实际的环境情况测试，设备在环境中可能是工作状态，也可能是非工作状态，在模拟工作状态时，设备一边供电一边浪涌测试，这时需要防止浪涌倒灌入市电中对其他非实验设备造成破坏，所以，需要对其进行隔离，用到的设备叫耦合器，他的接线示意图如下；

四、整改过程

1、现整改的样机是一款高压灯带驱动器，需要对其进行浪涌抗扰度的升级，根据国标浪涌的试验等级表，以及客户测试的浪涌电压2kV，我们对应出这次的升级的等级为4等级，这是感应雷试验等级的最高等级。但不是说环境中感应雷的最高等级，环境中的感应雷等级一般很难获得，需要专业的设备捕捉，但不管现实如何，我们就按这次的要求整改。

2、加电容电感降残压

灯带电路原来板子上还留有一个电感与电容的位置，为了节省成本去掉了，现要过浪涌，就给客户加上去，然而测试后功率开关还是损坏。如下图；

原电路图

加上电感电容电路图

3、提高反向耐压

用电感电容降压后发现+2能过，而-2kV不能过。所以得提高功率开关的反向耐压，这里我们用了一个二极管来提高反向耐压，并且对后面可以起到防反接的作用，同时保护了电解电容。如下图；

四、总结案例

1、这里是功率开关损坏，那自然对其进行保护，主要是降低残压。

2、通过一些降低残压的措施后，发现测试现象发生变化，这时我们要根据现象判断问题，这里是反向耐压不足，那么我们提高反向耐压就解决了。

【经验】压敏电阻防雷的工作原理及特点

压敏电阻器相当于一个可变电阻，它是并联于电路中的，当电力线被雷击时，雷电波的高电压使压敏电阻击穿，雷电流通过压敏电阻流入大地，使电力线上的电压被钳制在安全范围内。压敏电阻的性能稳定、通流能力大，由于其突波承受能力取决于它的物理尺寸，因而有可能获得不同的浪涌电流值。

【经验】压敏电阻在过压保护中的使用要点

过压保护压敏电阻的使用原则是在其接入被保护设备后，不能影响设备的正常运行，又能有效地对设备实施瞬时过压保护。为此，除了过压保护压敏电阻的技术参数外，在实际选择时还要考虑通流容量、固有寄生电容和压敏电压的选择。硕凯电子压敏电阻（MOV）广泛应用于电源线及信号线路的过压保护，质量有保证，经RoHS、REACH等认证通过。

【经验】一文解析压敏电阻的选型要领

作为一种应用范围十分广泛的压敏电阻器，过压保护压敏电阻也经常被用于保护可控硅整流器之中，其中，3kA的压敏电阻型号通常会被用在电器设备的浪涌吸收上，而5kA的电阻型号则多被用在对雷击及电子设备的过电压吸收上，10kA的则会被用在对雷击的保护上。这里硕凯电子以雷击保护为例来进行说明。

基于硕凯压敏电阻14D561K的IGBT快速开关电路，在浪涌抗干扰度试验中通过4级，且试验电压提高10%

本试验选用压敏电阻14D561K：击穿电压：504V-616V；通流量IPP高达4500A；位电压最大值 925V（50A）；工作温度：-55 至+125°C；具有通流量大、残压低、响应时间快等特点。当干扰电压达到一定值时，就会把两端的电压钳位住，从而保护IGBT不被击穿

【应用】国产压敏电阻14D561K用于LED路灯，通流量可达6KA

由于LED灯具有节能、响应时间短、使用寿命长、可直接替换传统灯等优点，所以LED灯的应用越来越广泛，现如今LED路灯也是随处可见。本篇主要讲述硕凯电子14D561K压敏电阻在LED路灯的应用，具有大通流量雷电在电源线路上产生感应浪涌，这个浪涌的能量会在电线上产生一个突波，即浪涌波，浪涌就是通过这样的感应方式进行传输的。
