Abstract

This paper presents a novel synchronous DC link voltage notching circuit topology for zero voltage switching (ZVS) of PWM inverters. The link voltage will fall to zero almost immediately after the controlled switch is turned on. Thus, the synchronous operation of the link voltage with any PWM pattern is facilitated. Analysis and simulation have demonstrated the successful operation of the new topology. The feasibility of the proposed scheme is experimentally verified on a laboratory prototype
