A Modular Converter Topology with Fast Discharging and Regenerative Capability for any n-Phase SRM Drive

Abstract

This paper presents a novel converter topology having less switches per phase and a common fast discharging circuit suitable for Switched Reluctance Motor (SRM) drives. The topology makes use of fly back circuit principle for fast discharge of winding current back to the source. The proposed topology can be modularized for any n-phase SRM drive keeping the same discharging circuit. The converter is analyzed and is implemented on a 4 phase 8/6 SRM drive using PSPICE and MATLAB/Simulink and the results are reported.
