Abstract

Using a Assistance Power Sources of the Railroad Vehicles Three-Level ZVZCS DC/DC Converter is presented in this paper. The proposed three-Level DC/DC Converter Is to achieved zero voltage and zero current switching for the two Main switches. phase shift method is used a parastic capacitance by reverse recovery characteritics in a inner diode of the switching device. Also. using a diode second part of the Transformer by the simple auxiliary circuit for the achieved zero current switching of the Auxiliary switch. For the ZVZCS movement of the all switching devices is analyzed and verified under a 5kW, in the 100kHz switching frequency.
