OBC（车载充电机）充电时需要接入电网，由于电网可能存在的瞬态浪涌，需要在OBC输入端口加入瞬态电压防护措施。一般来说，推荐MOV+GDT双重防护措施去解决。本文介绍LITTELFUSE 提供的OBC输入端口浪涌防护解决方案。

图1 OBC整体方案框图

应对电网瞬态浪涌，端口需要的防护功能保护：

（1）压敏电阻MOV+气体放电管GDT需要承受电网瞬态8/20us波形冲击；

（2）需要在高温条件下工作，满足125℃工作要求；

（3）工作电压需要满足AC输入电压要求；

（4）通过AE-Q200认证。

推荐Littelfuse AUMOV +GDT CG2/CG3系列设计，端口输入电压防护应用推荐如下：

图2 电源端口输入浪涌防护推荐应用

AUMOV+CG2/CG3系列产品在OBC输入端口浪涌抑制具备以下几点优势：

（1）AUMOV系列压敏电阻工作电压14~625V，满足220VAC/380VAC输入要求。

（2）直径5/7/14/20mm满足不同电压钳位功率要求。最大脉冲冲击电流可以达到10kA（8/20us波形条件下）；

（3）双层涂层提供了很高了电气隔离能力，达到2500V电气隔离。同时满足最大125℃的运行要求。

（4）通过AE-Q200认证；

（5）配合气体放电管CG2/CG3使用，最高最大20kA的放电电流。

另Littelfuse在车载OBC应用上提供了一系列的保护方案，具体可见平台【选型】Littelfuse（力特）汽车市场电路保护器件选型指南。

【选型】如何选用合适的气体放电管进行开关电源雷击浪涌的保护

笔者在开关电源设计项目中，做电源输入的保护时，涉及到雷击浪涌保护器件气体放电管的选型设计。由于Littelfuse的气体放电管型号很多，因此如何选择一款合适自己项目使用的气体放电管也是困扰设计工程师的一大难题。笔者此前负责的多个项目中，为了实现开关电源的输入雷击浪涌保护，多采用Littelfuse的气体放电管，积累了一定的选型和应用经验，借此分享给大家，希望对在一般选型应用中提供一些帮助。

压敏电阻的故障有哪些表现形式？

压敏电阻在超寿命使用或异常使用下，可能出现失效情形，常见的失效模式有两种：1、开路模式。开路模式主要发生在MOV流过远远超出自身承受的浪涌电流时，通常表现为氧化锌压敏电阻本体炸裂，但这种模式不会引起燃烧现象。2、短路模式。短路模式大体上可分为老化失效和暂态过电压破坏两种类型。高质量的压敏电阻，可提高抗失效能力，相关推荐型号如下：https://www.sekorm.com/doc/680916.html 《【选型】Littelfuse（力特）压敏电阻-金属氧化物压敏电阻（MOV）选型指南》

三相380V压敏电阻配置、型号和接线方式？

三相380V压敏电阻接线方式一般是单根火线对零线并接，三相就是分别并三个，配置主要参数第一个是稳定电压值，一般选431或者471，第二个浪涌电流根据负载特性选择，第三个就是漏电流参考；型号选择推荐Littelfuse的压敏电阻，具体型号可参考：https://www.sekorm.com/doc/previewDoc?docId=680916

【应用】符合车规认证的AUMOV系列压敏电阻为车载OBC保驾护航

车载OBC又称车载交流充电机，安装于电动汽车上，通过插座和电缆与交流插座连接，以三相或者单相交流电源向汽车提供电源；车载OBC的优点是不管车载电池在任何时候，任何地方需要充电，只要有充电机额定电压的交流插座，就可以对电动汽车进行充电。由于接的是电网电压，因此需要对OBC输入端进行防雷设计，本文简述了Littelfuse的AUMOV系列压敏电阻在车载OBC上的防雷设计应用。车载OBC输入一般以电网电
