1. An electric power supply apparatus for supplying an electric power to a load based on an alternating magnetic field created by an induction heating cooking appliance which is equipped with a proper pan detection function to detect that an article to be heated is put on the induction heating cooking appliance as a proper magnetic material cooker when an electric power consumed by the article put on the induction heating cooking appliance, upon being irradiated with intermittent magnetic force lines, falls within a given range, which apparatus comprises:

  • a power generation coil that generates an induction current by crossing the power generation coil and an alternating magnetic field created by said induction heating cooking appliance, and that supplies it to said load;

    a breaker section connected between said power generation coil and said load;

    a detection section that detects physical quantities created in said power generation coil, said breaker section and/or said load; and

    a control section that controls an electrical disconnection between said power generation coil and said load based on signals output from said,detection section,characterized by the fact that, when a consumption power, which is consumed by said load when the electrical disconnection is established between said power generation coil and said load by said breaker section, falls outside a set range which is set by using as a standard a consumption power consumed by a magnetic material cooker put on said induction heating cooking appliance, said induction heating cooking appliance recognizes that the magnetic material cooker is not put thereon, to thereby stop the generation of the alternating magnetic field.
