<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating device of an inverter system capable of efficiently supplying desired power to object to be heated different in materials. <P>SOLUTION: The induction heating device is provided with a resonant load circuit containing an object to be heated and an inverter inverting a direct current voltage into an alternate current voltage and supplying power to the resonant load circuit. The inverter is provided with two top and bottom arms constituted of at least two switching elements connected in series, an inductor connected to a direct current power source and a switch changing over the other connecting point of the inductor, which is changed over depending on the material of the object to be heated. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
