The present invention intends to reduce the unbalance among phase currents without the use of a Scott-connection transformer. The present invention is an induction heating system 100 adapted to use a three-phase AC power source 4 to operate a first induction heating apparatus 2 including a first induction coil 21 and a second induction heating apparatus 3 including a second induction coil 31. In addition, the number of turns of the second induction coil 31 is an even number. Also, one of the winding start point 21x and winding end point 21y of the first induction coil 21 is electrically connected to one phase of the three-phase AC power source 4, and the other one is electrically connected to the midpoint 31z of the second induction coil 31. Further, the winding start point 31x and winding end point 31y of the second induction coil 31 are electrically connected to the remaining two phases of the three-phase AC power source 4. |
