Abstract
According to the present invention, an induction heating apparatus comprises a rectifying circuit for rectifying an AC voltage from an AC power source, an inverter circuit for converting a DC output from the rectifying circuit to a high frequency current and supplying it to a heating coil, a circuit for detecting a fluctuation in the AC power source through a low voltage converting section coupled to the AC power source, this detecting circuit having a detection characteristic which can hold the detecting state for at least a constant time, and a controlling circuit for controlling the inverter circuit in the stopped state or driving state in accordance with the presence or absence of a detection output from the circuit for detecting the fluctuation in the AC power source voltage.
