A control circuit for an induction heating device includes a D.C. power supply, referenced to a ground connection and configured to supply power to the induction heating device. A switching device is configured to be selectively activated to control the induction heating device. The switching device is connected on one end to the ground connection. A resonant load is disposed between the D.C. power supply and the switching device, the resonant load including a capacitor and an inductor connected in a parallel configuration. At least one rectifying device is disposed in series with the resonant load and the switching device. The switching device is configured to control current from the D.C. power supply through the resonant load.
