Abstract
It is importent to have the switching frequency of power supplies increase in order to reduce their size and weight. But according to increasing the switching frequency, there are several defacts - that is switching losses, high voltage/current stresses and conduction losses and so on. That's why soft switching method was proposed. This paper presents the simulation and analysis of the new proposed Full bridge Zero-Voltage-Transition PWM DC-DC converter for developing that unit. This circuit doesen't increase the voltage and current stresses of main MOSFET switches. Voltage type quasi-resorent method is applied and expected high effenciency. Switching frequency is 100KHz and main switches are MOSFET.
