A resonance power supply for generating variable AC power to apply to an induction coil magnetically coupled to a work piece comprising: at least one rectifier (55) with power factor correction (PFC), at least one step down voltage regulator (68), at least one resonant inverter (53), at least one induction coil magnetically coupled with at least one work piece (13), and at least one control circuit (52) configured to adjust at least one parameter associated with at least one of the rectifier and the resonant inverter responsive to the output of the resonant inverter. |
