Abstract :
In this paper, the analysis of the steady-state characteristics for two-transformer asymmetrical half-bridge DC/DC power converters is presented. Based on the mathematical derivations, the ZVS condition of the power switches is quantized and a design procedure can be developed accordingly. The experimental results obtained from a 200 kHz 24 V/10 A prototype power converter with 92% efficiency is used to verify the analytical derivations.
