摘要
本文介绍了三相桥式逆变器中功率器件关断时浪涌电压产生的原因，同时分析了3种关断缓冲电路中功率器件通断时电路的工作过程和特点，最后给出了缓冲电路的功耗计算方法及缓冲电路阻容元件选取原则。
This paper introduces the cause that makes surge voltage in three-phase fullbridge inverters main power components, meanwhile analyzes on-and-off process and characters of main power components with three various types of buffer circuit. At last the method of calculating losses, a principle of choosing capacitance-resis-tance components for buffer circuit are also given out.
