Abstract :
A zero-voltage switched (ZVS) PWM boost power factor correction (PFC) converter is proposed in this paper. ZVS operation is achieved with a simple auxiliary resonant circuit that is activated for only a small fraction of the switching period and handles much less power than the main power circuit. The practical issues involved in designing and operating the converter such as the design of the power circuit and the implementation of the control circuit are examined in the paper. The feasibility of the converter is shown with results obtained from an experimental prototype
