This paper presents the system analysis and circuit design of a half-bridge zero voltage switching (ZVS) flyback converter with synchronous rectifier. The leakage inductance and output capacitance of active switches are used to realize ZVS operation during the transition state between two switches. The switching power loss of active switches can be reduced to minimum due to the ZVS operation such...
A study of the half-bridge converter to achieve zero voltage switching at turn-on is presented. The asymmetrical pulse-width modulation technique is used in the converter to regulate the output voltage and improve the duty cycle utilization. The analysis is presented for the switch stress, output filter components and rectifier diodes. The principle operation based on the mathematical analysis is...
