Abstract

Firstly, a new zero-voltage-transition (ZVT) power converter for switched reluctance motor drives is presented. The proposed ZVT converter possesses the definite advantages that both main transistors and diodes can operate with zero-voltage switching (ZVS), unity device voltage and current stresses. Secondly, its zero-current counterpart is also presented, which offers both the main and auxiliary switches operating with zero-current switching (ZCS) and minimum current/voltage stress. They both have simple circuit topology, minimum component count and low cost. This family of power converters is especially advantageous for switched reluctance motor drives demanding efficient regenerative braking, such as in electric vehicle applications
