Pseudo-Partial-Power Switch-Multiplexed Resonant Converter with Wide Voltage Gain

Year: 2025

Type: article

Abstract: Full-bridge resonant converters have gained widespread adoption due to their excellent performance characteristics. However, these converters face limitations in terms of gain expansion. To address this issue, this paper proposes a switch-multiplexed resonant converter with wide voltage gain. By employing an auxiliary capacitor and inductor, the converter can achieve pseudo partial power processing and effectively expand its voltage gain. To regulate the voltage of the converter, the duty cycle of the switching devices is designed to be modulated, which is different from the conventional resonant converter. By optimizing the design parameters, the resonant current of converter can operate in discontinuous current mode (DCM), eliminating reverse recovery losses and/or minimizing reactive current. All switching devices achieve soft switching, thereby removing switching losses and further enhancing efficiency. Finally, a 1 kW prototype is built to validate the effectiveness of the proposed converter.
