Abstract :
A novel zero-voltage zero-current transition (ZVZCT) soft-switching cell was presented in this paper. Based on the soft-switching cell, novel ZVZCT PWM converter family was built. The converter family has such advantages as zero-voltage zero-current switching in main switch, zero-current turn-on and zero-voltage zero-current turn-off in auxiliary switch, zero-current zero-voltage turn-off and zero-voltage turn-on in freewheeling diode as well. In addition, pulse width modulation (PWM) control was achieved. The operation principles and experimental verification of buck ZVZCT PWM converter was given as an example of the proposed ZVZCT PWM converter family in detail. Experimental results completely verify theoretical analysis
