PROBLEM TO BE SOLVED: To provide a heat induction system that can reduce unbalance of phase current with no Scott connection transformer.SOLUTION: In an induction heating system 100 for operating a first induction heating device 2 having a first induction coil 21, and a second induction heating device 3 having a different magnetic circuit from the first induction heating device 2 and a second induction coil 31 by a three-phase AC power source 4, the number of turns of the second induction coil 31 is an even number, one of a winding starting end portion 21x and a winding terminating end portion 21y of the first induction coil 21 is electrically connected to one phase of the three-phase AC power source 4, and the other end portion is electrically connected to a midpoint portion 31z of the second induction coil 31. A winding starting end portion 31x and a winding terminating end portion 31y of the second induction coil 31 are electrically connected to the remaining two phases of the three-phase AC power supply 4.SELECTED DRAWING: Figure 1 |
