<p><P>PROBLEM TO BE SOLVED: To provide a large electromagnetic induction heating device capable of reducing manufacturing cost, and of being downsized. <P>SOLUTION: This large electromagnetic induction heating device is an electromagnetic induction heating stove provided with: two sets of power circuits 10 and 30 converting input A.C. power to D.C. power; two sets of inverter circuits 20 and 40 converting the D.C. power to high-frequency power by switching it by IGBTs 21, 22, 41 and 42; two sets of work coils 15 and 35 electromagnetically induced by the high-frequency power; and a single control circuit 50 controlling the inverter circuits 20 and 40. The single control circuit 50 synchronously drives the two inverter circuit 20 and 40. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
