<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device capable of miniaturizing a circuit. <P>SOLUTION: The induction heating device comprises an inverter converting an output of a rectifying circuit 2 into high-frequency power and applying power to a heating coil, a current detection means 3 for detecting an input current from an AC power source, and a control means 8 for controlling a conduction time of a plurality of semiconductor switches in first and second inverters according to outputs of the current detection means 3. After an input current of the first or the second inverter reaches a target value, the control means 8 can supply designated power to respective inverters even if simultaneous operations of two inverters are performed by the rectifying circuit 2 and the current detection means 3 which have their own structures, and the circuit of the induction heating device can be miniaturized. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
