An exhaustive method for the selection of different power semiconductor switches for high frequency hybrid resonant inverter fed induction heater is presented here. Heating coil of the induction heater is made of litz wire which minimizes the skin effect and proximity effect at high operating frequency. With the calculated optimum values of inductance and resistance of heating coil at a particular operating frequency, high frequency hybrid resonant inverter topology has been simulated using PSPICE software as well as constructing the experimental model of same rating. Obtained the voltage waveforms across heating coil and current waveforms through it, have been taken for further analysis.
