Abstract :
This paper presents a new family of PWM soft-switching power converters which can operate without switch voltage and current stresses in high switching frequency for a wide range of load. To illustrate the operating principle of these new power converters, a detailed study including simulations and experimental tests is carried out for the boost converter. The validity of these new converters is guaranteed by the obtained results
