- Abstract
- This paper proposes a novel soft-switched auxiliary resonant circuit to provide a Zero-Voltage-Transition turn-on switching for a conventional PWM boost converter in a PFC application. The proposed auxiliary circuit enables a main switch of the boost converter to turn on under a zero voltage switching conduction and simultaneously achieves both soft switched turn-on and turn-off. Moreover, for the purpose of an intelligent power multi-chip module fabrication, the proposed circuit is designed to satisfy some design aspects including space saving, low cost, and easy fabrication. As a result, the circuit is easily realized by a small rated MOSFET and tiny inductance. Detail operation and waveform are theoretically explained and, simulation and experimental results, by the 1.8 kW prototype PFC boost converter, are provided to verify the effectiveness of the proposed circuit.
