Abstract
In this paper, a new soft switching isolated PWM converter without any auxiliary switch is proposed. The auxiliary circuit contains of two coupled inductors and one snubber capacitor. In this converter, switch is turned on under zero current switching and turn off under almost zero voltage switching. Switch is PWM controlled which simplifies the control implementation. One of the main advantages of this converter is the possibility of sharing the output power between the magnetic devices and operating at high power levels. The simulation results obtained from the proposed converter verifies the theoretical analysis.
