对于整流二极管,电容器和IGBT(绝缘栅双极晶体管),额定电压应大于此值,以便为整个系统提供足够的电压保护。有时,很难为整个系统提供电压保护,尤其是对于600V或更高的高功率线路电压应用而言。对于这些情况,雷卯电子建议使用附加的(或次级)大功率TVS二极管,该二极管具有的低压钳位能力,可为整流二极管,电容器和IGBT提供差分保护。
如上面图中的粉红色方框所示,可以添加两个AK3-380C TVS二极管,以在大3kA,8 / 20µs的浪涌电流期间提供差分保护。AK3-380是一款双向大功率TVS二极管,额定值为3kA(8 / 20µs),隔离电压为380V。两个AK3-380C TVS二极管的大钳位电压为1040V,远低于MOV。
结果,它们为6装IGBT提供了出色的浪涌保护,同时将电路保持在正常工作条件下。添加这些TVS二极管可为设计人员在选择整流二极管和IGBT时提供更大的灵活性。
