Abstract

Resonant inverters are widely used in induction heating applications. Series Resonant Inverter (SRI) fed with voltage source is very much reliable, cost-effective and provides various power control techniques. Different power control schemes like phase shift control (PSC), asymmetrical duty cycle (ADC) control, asymmetrical voltage cancellation (AVC) control, pulse density modulation (PDM) control are normally used at SRI for high frequency induction heating. In this paper a new hybrid control technique by combining PSC and PDM is analyzed. The new control technique overcomes the drawback of individual scheme and provides a wide range of power control. The analyses of all the control techniques are verified through MATLAB simulation results.
