| Abstract: | The soft-switching techniques have been developed from the basic resonant converter, quasi-resonant converter, multi-resonant converter and resonant dc link converter to the soft-switching PWM converters. The soft-switching PWM converters combine the merits of the soft-switching techniques and the PWM techniques, which become a class of the most prospective converter in engineering applications. This paper reviews the basic principles and characteristics of the soft-switching PWM converters including the resonant dc link converters, zero-voltage-switched (ZVS) quasi-square- wave converters, ZVS-PWM converters, zero-voltage-transition (ZVT) PWM converters and zero-current-transition (ZCT) PWM converters. |
