Abstract
Disclosed is an inductive heating device which can lower losses in the device and readily provide cooling, wherein a controller is operated in a first control mode which controls the operation so that a unipolar first switching element and a unipolar second switching element conduct alternately when one of a bipolar third switching element and a bipolar fourth switching element is conducting and the other is disconnected when an aluminum object to be heated is heated, and in a second control mode in which the conduction of the first switching element and the fourth switching element and the conduction of the second switching element and the third switching element alternate when an iron object to be heated is heated.
