Considering half bridge converters for switched reluctance motor drive applications

Abstract

The aim of the paper is to present an option of using regular half-bridges topology converters for independent driving of multi-phases switched reluctance motors (SRMs). The possibility of using a well-known and accepted topology could represent a cost-related, self-assured and more-efficient way of addressing at least some of the issues regarding the SRM acceptance in practical implementations. In this paper, the general approach, working principles, the first developments and analyses are introduced. Numerical simulations have been done considering the whole drive and the differences between the conventional and the studied converters are highlighted, when applying the converters output voltages to a three-phase 6/4 SRM.
