A novel single-stage half-bridge high frequency resonant inverter using ZVS(Zero voltage Switching)with high input power factor suitable for induction heating applications is presented in this paper. The proposed high frequency resonant inverter integrates half-bridge boost rectifier as power factor corrector(PFC)and half-bridge resonant inverter into a single stage. The input stage of the half-bridge boost rectifier is working in discontinuous conduction mode(DCM) with constant duty cycle and variable switching frequency. Simulation results through the Pspice have demonstrated the feasibility of the proposed inverter This proposed inverter will be able to be practically used as a power supply in various fieleds as induction heating applications, DC-DC converter etc.
