<p><P>PROBLEM TO BE SOLVED: To solve a problem that, in the case of a conventional induction heating cooking oven, resonance voltage of a switching element gets large, and so, a rating of the switching element used gets large. <P>SOLUTION: A clamp circuit constituted of a series circuit of a clamp capacitor 10 and a second switching element 11, and a second diode 12 connected in parallel with the second switching element 11 is connected with a first choke coil 3, and resonance voltage of a first switching element 4 is lowered, so that the first switching element 4 can be one with a low breakdown voltage rating in the induction heating cooking oven. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
