INDUCTION HEATING APPARATUS AND INDUCTION HEATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an induction heating device capable of properly cancelling a mutual induction voltage regardless of the magnitude of the mutual induction voltage.

SOLUTION: An induction heating device 10 has a plurality of induction heating coils 56 arranged adjacent to each other, and generating a mutual inductance. A circuit having the induction heating coils 56 arranged adjacent to each other has a reverse coupling transformer 64 generating a mutual inductance with an opposite polarity between the induction heating coils 56 arranged adjacent to each other, and coupling coefficient variable means for changing a coupling coefficient of the reverse coupling transformer 64. The coupling coefficient means changes the coupling coefficent of the reverse coupling transformer 64 so that a mutual inductive inductance generated between the induction heating coils 56 is identical to a mutual inductive inductance with an opposite polarity generated between the reverse coupling transformers 64.
