基于电流矢量相位的电压源逆变器弱开路故障诊断

This article presents an open-circuit fault diagnosis approach for the drive inverter system in a permanent magnet synchronous motor. This method can detect weak faults, and extract key features based on the current vector phase. Initially, the three-phase current signal is collected as the original input, and the current vector phase is calculated. Subsequently, fault detection employs time-domai...
