This paper presents modelling and simulation of high frequency inverter for induction heating applications. Induction heating has advantages like higher efficiency, controlled heating, safety and pollution free therefore this technology is used in industrial, domestic and medical applications. The high frequency full bridge inverter is used for induction heating, also MOSFET is used as a switching device for inverter and the control strategy used for inverter is Bipolar PWM control. The size of converter and component size are reduced by using higher switching frequency. The series resonant tank is designed and is connected to the output side of transformer to produce higher amount of current in work piece to be heated. Keywords: Full bridge inverter, High frequency, Induction heating, Pulse Width Modulation (PWM).
