基于原侧电感能量分析的两电平三相PWM升压整流器实时多开路故障诊断

Two-level three-phase boost rectifiers are widely used in industrial applications due to their superior performance. According to the survey reports, the transistors often suffer from open-circuit failures due to the lifting of bonding wires caused by thermic cycling, resulting in output fluctuation and current harmonics. This paper proposes a real-time, robust fault diagnosis method for single an...
