Abstract :
This paper presents a new boost PWM soft-single-switched power converter which, having only a single active switch, is able to operate with soft switching in a pulse width modulation way. In addition, such a power converter can work at high switching frequencies for a wide range of load. In order to illustrate the operating principle of these new power 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
