Half bridge soft switching resonant converter with silicon carbide power MOSFETs for induction heating

摘要

In this paper, a half bridge soft switching resonant converter for induction heating load with SiC MOSFET devices is proposed. In order to raise the efficiency of the proposed converter, a single phase half bridge resonant converter integrated with SiC MOSFET is used. All of the switching devices in the proposed converter achieve zero voltage switching (ZVS). Thus, the proposed circuit has a high efficiency characteristic due to low switching losses. To verify the validity of the proposed topology, the prototype is tested around 650 W and 53 kHz of operating frequency. The experimental results shown that the proposed converter with SiC MOSFET has high efficiency characteristics.
