Abstract :
A novel DC bus snubber subcircuit for high-frequency high-power half-bridge forward PWM DC-to-DC converters is presented. This snubber consists of a DC bus interrupt switch and a capacitor connected across the converter. The effective use of these components yields zero voltage switching conditions for both the DC switch and the high-frequency inverter. Additionally, the DC bus switch can be utilized to isolate the inverter under abnormal operating conditions. Complete circuit analysis, design procedures, and a simulated verified design example are included
