Abstract
The present invention intends to run one induction heating apparatus using a three-phase AC power supply without use of a Scott connection transformer while preventing an occurrence of a phase where no current flows. An induction heating system uses the three-phase AC power supply to run the induction heating apparatus including an induction heating coil, and has an intermediate apparatus including a coil that is wound on an iron core with an even number of turns, forming a closed magnetic circuit. Additionally, a winding start point of the induction heating coil is connected to the U phase of the three-phase AC power supply and a winding end point of the same is connected to a midpoint of the intermediate coil. The winding start point and end point of the intermediate coil are connected to the V and W phases of the three-phase AC power supply, respectively.
