초록
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.
