چکیده
This paper is proposed to improve the efficiency of the series resonant inverter for industrial heating applications. Resonant inverters are those operate at high frequency with reduced losses preferable for induction heating. Resonating components and switching device which are placed in series to load forms series resonant inverter. Inverter which is characterized by full bridge made up of Insulated Gate Bipolar Transistor (IGBT). Due to an induction heating the amount of controlling the power is one of the desirable things. Power control strategy is achieved by hysteresis current control which controls the output power for a wide range. Switching losses are minimized by performing zero voltage switching and zero current switching. Improvement in efficiency by choosing appropriate values of modulation index.
