PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating control device that can be of low cost and low power consumption and does not generate a high harmonic wave noise in adopting a series resonance circuit type which is more advantageous than a parallel resonance circuit type in designing the number of turns and shape of the electromagnetic induction coil. SOLUTION: In the electromagnetic induction heating control device, a series resonance circuit type which is more advantageous than a parallel resonance circuit type in designing the number of turns and shape of the electromagnetic induction coil 11 is adopted, and a front drive circuit 13 which forms a parallel resonance circuit together with the input capacity of the FET Q11, Q12 is provided to the drive circuit 12 that is made of FET Q11, Q12 of complementary symmetric connection and drives the series resonance circuit 11, thereby, drive of the FET Q11, Q12 can be made possible even if the input capacity of the FET Q11, Q12 is large. |
