Abstract
Recently, a number of soft switching pulse-width-modulated (PWM) power converter techniques have been proposed, aimed at combining the desirable features of both the conventional PWM and resonant converters while avoiding their respective limitations. In this paper, four classes of soft switching PWM converters are reviewed, including the zero-voltage-switched (ZVS) quasi-square-wave converters (QSCs), ZVS-PWM converters, zero-current-switched (ZCS) PWM converters, and zero-voltage-transition (ZVT) PWM converters; their merits and limitations are assessed. Experimental results of several prototype of converters are presented to illustrate each class of converters
