A New Modular Asymmetrical Half-Bridge Switched Reluctance Motor Integrated Drive for Electric Vehicle Application

Abstract

A modular asymmetrical half-bridge drive topology for a 12/8 switched reluctance motor (SRM) is introduced in this paper. The drive operates both in driving and charging modes and does not require any circuit reconfiguration to switch between the two modes. In addition to high degree of fault tolerance, voltage equalization of the battery packs can be achieved with ease in both idle and charging modes. The operation of the proposed converter topology and its performance is investigated with simulations. A power factor correction strategy is applied to shape the grid side current. The simulation results show the driving and charging performance and state of charge equalization capability of the proposed integrated SRM drive
