【应用】基于BOD击穿二极管IXBOD 1-06的直流硬件过压保护电路的设计方案
近年来，新能源技术和储能技术发展迅速，中高压AC/DC、DC/AC换流器应用越来越广泛。在中高压直流电力电子应用领域，直流过压保护功能是必不可少的。通常，产品应同时具备软件过压保护和硬件过压保护，其中硬件过压保护应独立于其他电路工作，即使其他电路电源缺失，硬件过压保护电路仍然可以工作。而如何用简单可靠的方法实现硬件过压保护，对于简化产品设计，降低产品成本尤为重要。本文将介绍一种BOD在直流硬件过压保护电路中的应用案例，该案例成功应用于高压整流器的直流过压保护。
设计方案
硬件过压保护电路，设计要求该电路能独立工作，不依赖于其他电路。首选方案是利用无源器件实现，本方案选择了世强代理的IXYS公司保护器件Breakover Diodes (BOD)，BOD属于击穿二极管的一种，其工作特性如图1所示。当两端电压低于动作电压时，器件进入断开状态，漏电流很小，相当于断路；当两端电压高于动作电压时，器件进入导通状态。该产品击穿电压高，可应用于暂态过压保护等领域。
图1 BOD工作特性
下图是应用BOD实现过压保护的电路。电路原理比较简单：
图2 基于BOD的硬件过压保护电路
当HVDC电压正常时，BOD两端电压差小于其动作值，器件处于断开状态，SCR_G输出为零。当HVDC超过一定的电压，BOD两端电压差大于其动作值时，器件动作进入导通状态，对CX7进行充电，SCR_G输出脉冲信号，触发保护晶闸管（图中未画出），实现过压保护功能；由于此时CX6放电，CX7充电，BOD两端电压差减小到一定程度后，BOD断开，CX6由HVDC充电，CX7对外放电，BOD两端电压差又逐渐增加，如此往复。因此，BOD的动作是重复的。
参数选择
图2中，直流电压额定值为1500V，过压保护定值1800V，通过电阻2:1分压后为600V，因此选择的BOD器件型号为IXBOD 1-06，其动作电压600V±50V，漏电流20uA，电流有效值1.4A，最大峰值电流200A（0.1ms），通态压降1.7V。
为了保证动作速度，DF1需要选择快恢复二极管。SCR_G的输出波形是一个上升沿较缓，下降沿较快的电压尖峰，R4、R5和CX7决定输出电压的持续时间，可根据实际需要进行配置，图中参数配置大约为100us。
应用中的问题
在实际应用中，发现上述电路后级连接的晶闸管有损坏现象。经仔细测试发现，SCR_G峰值约为15V，超过了晶闸管手册里给出的最高门极触发电压10V，重复触发容易导致门极损坏。通过在输出侧串联10V的稳压管，可以限制输出电压峰值在5V左右，可以在保证晶闸管可靠触发的同时，避免晶闸管损坏。修改后的图如下所示。
图3 基于BOD的硬件过压保护电路改进
总结
本文介绍了应用IXYS公司的IXBOD 1-06器件成功实现高压直流的纯硬件过压保护方案，该方案的主要优点在于电路设计简单可靠，由纯无源器件组成，不需要为硬件过压保护设计单独的电源电路。
