Abstract
Efficiency and soft-switching phenomena of asymmetrical half-bridge forward mode converters are seriously affected by circuit parameters. The design trade-off between the leakage and magnetizing inductance for practical applications is presented. The ZVS condition, duty cycle loss and hold-up time etc are utilized for deriving the optimal design rules. Experimental verification on a 5 V/20 A prototype is conducted and 86 % efficiency is achieved.
