摘要

In this paper, we investigated the stress problems of switching devices with high voltage and high current in traditional power factor correction (PFC) circuits under hard switching conditions. The circuit uses the principle of capacitance inductance resonance and adding an auxiliary circuit to realize the zero voltage switching. The working principles of each stage of converter are analyzed, and the key component parameters of auxiliary circuit are studied and designed. A MOS transistor driving circuit based on UC3854 is also designed. Finally, the whole circuit is simulated and tested by PSIM software. The results show that the proposed boost ZVT-PWM converter can effectively improve the power factor of circuit, solve the current and voltage overlap problem of the MOS transistor under the condition of hard switching, realize the zero voltage switching of MOS transistor, and reduce the switching loss.
