摘要：
This paper presents soft switching of modified half bridge fly-back converter. The power switches in this converter are turned on at ZVS and the rectifier diode is turned on and off at ZCS. The auxiliary switch is turned off at ZCS. The voltage stress across the switch is equal to the supply voltage and soft switching is achieved for all the switching devices. Compared to half bridge flyback converter, this modified circuit has improved efficiency. A 5V/2A prototype is implemented to verify the practical results.
