INDUCTION HEATING METHOD FOR LIVING BODY AND APPARATUS THEREFOR

PROBLEM TO BE SOLVED: To put the advantage of induction heating in low output enabling treatment without selecting a place to practical use to selectively heat a focus such as cancerous cells without generating touble in normal cells. SOLUTION: A series resonance circuit 25 constituted of a heating coil 23 for generating an AC magnetic field in order to perform the induction heating of DM in a living body and a resonance condenser 43 is connected to the secondary side of a high frequency transformer 45 and the phase of the AC current on the primary side of the high frequency transformer 45 and the phase of the gate signal from a gate driver 41 to each FET 39a of a high frequency inverter 39 are adjusted while compared by a PLL control part 75 so as to coincide with each other so that the magnitude of the AC current flowing through the primary side of the high frequency transformer 45 becomes a large value appearing when the switching frequency of the FET 39a of the high frequency inverter 39 coincides with the frequency of the AC current on the secondary or primary side of the high frequency transformer 45 equal to the resonance frequency of the series resonance circuit 25.
