1. A method for controlling an induction heating device comprising:
supplying current from a D.C. power supply into an input node of a resonant load;
emitting the current from an output node of the resonant load;
directionally conducting the current in a unidirectional path from the output node of the resonant load to a switching node downstream along the unidirectional path from the output node; and
controlling the current conducted through the resonant load with a switching device.
