A serial regulator using a soft switching PWM AC/AC full bridge-converter

Abstract

This paper presents a soft switching PWM AC/AC full-bridge circuit that will be employed at the development of a serial regulator to contribute supplying 20% of total load power when vi(t)=180 V and consuming 10% of the power supplied to load when vi(t)=240 V. It does not contribute anything when vi(t)=220 V. Principle of operation, theoretical analysis, and design procedure are provided. The soft switching PWM AC/AC full bridge regulator has been validated by simulation results.
