开关磁阻电机IGBT尖峰电压
来源: 作者: 发布时间:2021-07-11 06:36:54 浏览量:讨论一下开关磁阻电机的桥式拓扑结构中,IGBT的尖峰电压用RCD吸收回路三项的话用三个吸收回路比较好,还是只用一项好呢?那几种吸收回路,CRC那种更适合开关磁阻电机
参数不对了用多少都不行。
。
参数对了也许很简单。

恩,现在我们搞开关磁阻电机,每次IGBT都烧,很纠结啊好比我关断时候,尖峰立马产生,吸收回路如果吸收的慢,尖峰是不是立马就把IGBT烧掉,如果快的还好,但是为了快,又怕尖峰吸收的不彻底,现在上到200V出现堵转,很纠结啊

如果主电路结构设计合理尖峰不会太大。
吸收电路一般的用一个电容就可以
