Abstract :
In this paper, an analytical analysis and design for the zero-voltage switching (ZVS) asymmetrical half-bridge (AHB) PWM DC/DC forward converter is featured. To gain insight sufficient to understand as well as design the system. It concludes that the ZVS condition of the converter can definitely not be calculated by simply regarding the stored energy in leakage inductance. The derived closed-form relationships can also be used to guarantee required boundary conditions. As a result, the converter design can be optimized for ZVS in all desired operation ranges
