Reduced Switch Count Converter For Switched Reluctance Generators

Abstract

This paper deals with electronic converters to drive the switched reluctance generator -SRG. An alternative reduced switch count converter is compared with the conventional asymmetric half bridge converter. The SRG is driven with constant speed and excited with DC power from a three-phase rectifier bridge and supplies pulsed DC power to the load at the output. Mathematical and computing models for the SRG are presented, as well as simulation and experimental results. The aim is to show that the alternative converter, which is cheaper, works better than the half bridge converter commonly used to drive these machines.
