<P>PROBLEM TO BE SOLVED: To provide an induction heating apparatus which can attain compactness inexpensively and can maintain a suitable operational state in which influence of mutual induction is avoided. <P>SOLUTION: In an induction heating apparatus 10 having a plurality of induction heating coils 12 disposed close to each other and series resonant inverters 16 connected to the plurality of induction heating coils 12 respectively and performing current synchronization control, power and phase adjustment means 22 which outputs a signal for performing control of a frequency of output current and a pulse width of voltage from the inverters 16 is connected to the inverters 16 and power detection means 26 which outputs, when a border value of output power at the time of high output and low output from the inverters 16 is preliminarily set and the output power is within the range at the time of low output, a switch signal making the frequency of the current voltage output from the inverters 16 higher than that in the case where the output power is within the range at the time of high output to the power and phase adjustment means 22 is connected to the power and phase adjustment means 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
