Abstract

This paper presents a new family of PWM soft-single-switched power converters which, having only a single active switch, are able to operate with soft switching in a pulse width modulation way. In addition, such power converters can work under high switching frequencies for a wide range of load without great duty cycle limitations. In order to illustrate the operating principle of these new converters, a detailed study, including simulations and experimental tests is carried out. The validity of these new power converters is guaranteed by the obtained results
