<P>PROBLEM TO BE SOLVED: To provide an induction heating device restraining a switching loss of a switching element irrespective of a material of a heated object and an output. <P>SOLUTION: By controlling simultaneous breaking periods from breaking a first switching element 27 to driving a second switching element 42 alternately driving, or from breaking the second switching element 42 to driving the first switching element 37, starting of driving of the switching elements 37, 42 can be adapted to timing of conduction periods of reverse conduction elements 44, 45 even when conduction periods of a resonance current period and conduction periods of the reverse conduction elements 44, 45 are changed by electromagnetic characteristics of the heated object 39, and the induction heating device is restrained from a switching loss of the switching elements. <P>COPYRIGHT: (C)2004,JPO |
