چکیده

The isolated three-level DC/DC converter (ITLDC) can be used to charge electric vehicles. During the constant current charging stage, ITLDC designed realize nature zero voltage switching (ZVS). However, during is small; thus, ZVS cannot realized. This paper presents an active commutation auxiliary circuit (ACAC) for full load range ZVS. With proposed ACACs, all main switches achieve zero-voltage turn-on and quasi turn-off, turn-off; efficiency will high. currents generated by ACACs are controllable. realizes controlled zero; do not result in high stress or bring additional losses, decreases with time too small Thus, work within a suitable value whole process; structure operating principle of introduced performance TLDC experimentally verified on 1.5 kW prototype converter.

A New ZVS-PWM Full-Bridge Converter

A full-bridge converter which employs a coupled inductor to achieve zero-voltage switching of the primary switches in the entire line and load range is described. Because the coupled inductor does not appear as a series inductance in the load current path, it does not cause a loss of duty cycle or severe voltage ringing across the output rectifier. The operation and performance of the proposed ...
