<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating apparatus of low cost and high safety, capable of uniformly heating a heated object. <P>SOLUTION: A work coil 26 is so structured that a first coil 30 positioned in the middle and a second coil 32 positioned at an outermost side are connected in series with a basic coil 28 positioned at an innermost side, and at the same time, the first coil 30 and the second coil 32 are connected in parallel. To the first coil 30, a switching circuit 16 is connected for supplying high-frequency current, while, to the second coil 32, a second switching circuit 18 is connected for supplying high-frequency current. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
