基于相对β轴残余电压信号的逆变器开关开路故障检测

With the ever-increasing application of permanent magnet synchronous machine (PMSM) drives, the requirements for safety and reliability are raised. This article presents a detailed analysis of the open-circuit fault behavior of the inverter power device by comparing the reference voltage and the actual output voltage under both healthy and faulty conditions. The reference voltage is predicted by r...
