A new ZVS PWM voltage source inverter with active voltage clamping

摘要

This paper presents a new topology of a PWM-ZVS voltage source inverter, which has been generated by generalisation of the PWM-ZVS active clamping DC-DC converters. Besides operation with soft commutation for a wide load range, the proposedtopology has the feature of being modulated by any conventional PWM strategy employed in the hard-switching inverters. Operation description, analysis, design, simulation and experimental results are presented in the paper.
