Abstract

A new zero-voltage-transition (ZVT) soft-switching converter for brushless DC 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. It is a very desirable feature for high frequency switching power conversion where power MOSFETs are used. This converter is especially advantageous for brushless DC motor drives, such as electric scooter applications.
