<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating device in which a constant of a reactor composing a power source filter is made small and the device can be made smaller, lighter and more economical and an occurrence of interfering noises in case a plurality of inverters are driven simultaneously can be prevented. <P>SOLUTION: The electromagnetic induction heating device is provided with an inverter 50 for supplying a high frequency power to a heating coil 11 and the inverter 50 is provided with a resonance capacitor serial circuit consisting of serially connected resonance capacitors 4, 5, which is connected in series with a switching circuit of serially connected switching elements 6, 7. In addition to a serial circuit of the resonance capacitors 4, 5, a filter capacitor serial circuit consisting of serially connected capacitors 22, 23 is connected in parallel, and there is provided a reactor 24 for separating these resonance and filter capacitor serial circuits with respect to high frequency. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
