| Abstract |
A new zero-voltage zero-current switching full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. IGBT switches are used in the high-frequency inverter of the DC-DC converter. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to short circuit by using new secondary energy recovery clamp and modified PWM control strategy. Moreover by adding energy recovery clamp the zero-current turn-on and zero-voltage turn-off for rectifier switch is ensured. The principle of operation is explained and analysed and simulation results are presented. |
