Abstract Based on two-switch Flyback converter, a quasi-resonant soft-switched two-switch flyback converter is proposed by introducing a resonant network and replacing a clamp diode in the primary side with switch. The proposed converter retains the advantage of the two-switch Flyback converter, i.e. the voltage stress of switches is clamped at the input voltage. Therefore, the low-voltage-rated and low-on-resistance MOSFET can be utilized to improve the efficiency and reduce the cost. The proposed converter achieves zero-voltage-switching (ZVS) of all switches due to the resonance between the resonance inductance and the blocking capacitor, which can greatly reduce the turn-on losses of the switches. Furthermore, the leakage inductance energy can feed back to input voltage, the negative peak of resonance current and turn-off losses of the switches are hence reduced, then the efficiency of the converter is further improved. The operating principle and characteristics of the proposed converter working in unidirectional conduction mode are studied, especially the voltage stress and current stress of switches and the ZVS requirement. Experimental results of a 60W prototype are presented to verify the analysis of the proposed converter.

Key words： Resonance soft-switched two-switch flyback converter leakage inductance energy feedback
