ABSTRACT:
An inductive heating apparatus with multiple high frequency energy source. The apparatus includes plural resonant circuits each having an inductive heating coil and plural drive circuits for driving the resonant circuits. Switch circuits enable energization of one or more of the plural resonance circuits and a logic circuit is provided to ensure that whenever two or more resonance circuits are operated, they will operate at the same frequency to prevent unwanted noise otherwise resulting from the circuits operating at different frequencies.
