Power Electronic Converters for 12/8 Switched Reluctance Motor Drives: A Comparative Analysis

In this paper, five popular power electronic converters for three-phase 12/8 switched reluctance motor (SRM) drives including asymmetric power electronic converter, ${\rm N}+1$ power electroic converter, split AC power electronic converter, split DC power electronic converter, and C-dump power electronic converter are investigated and compared in terms of device ratings, cost, efficiency, torque ripples, average torque, and copper losses. Comparison results show that C-dump converter is a more promising candidate in high-performance SRM drives, while split AC converter is recommended in low-cost applications.
