New DC/AC Soft Switched PWM Converter Having a DC-Link Commutation Circuit

직류측에 Commutation 회로를 갖는 영전압 스위칭 PWM 인버터

A new dc/ac soft switched PWM convert having a dc-link commutation circuit is proposed. The commutation circuit implemented by utilizing a series resonant circuit while preparing for zero voltage switching of primary inverter. The converter provides both variable pulse width and position which is fundamentally different than converters. In this paper, the operating principles, design and control considerations analysis of a such a soft switched converter is analyzed.
