Based on a Novel Modular Converter, Modular Battery Management for SRM drives in Hybrid Vehicles

Abstract

Abstract: In order to address environmental issues, the automotive industry is moving in a significant direction towards hybrid vehicles. One of its primary drive system options is a switching reluctance motor (SRM). This article designs a brand-new SRM converter topology. The innovative converter can manage battery energy and implement multi-level control. The battery control circuit is created in a modular manner, allowing the number of battery modules (BMs) to be chosen based on system needs. A hybrid vehicle's driving conditions are used to separate the converter's status into five states and conduct detailed analyses of each. Ultimately, the novel converter's simulation model and testing platform are constructed. The findings of the simulation and experiment confirm the viability of various working modes of the system's fault tolerance and reliability have been considerably enhanced by the innovative converter topology and the ability to individually regulate each BM.
