    摘要: An induction heating cooker and a control circuit therefor are provided. The cooker includes a switch element and an inductive coil, which is coupled between a power voltage and a first terminal of the switch element. A second terminal of the switch element is coupled to a common voltage. The control circuit includes first and second comparators and a pulse generator. The first comparator receives voltages of two terminals of the inductive coil and thus outputs a trigger signal. The second comparator receives a reference voltage and a voltage of the first terminal of the switch element, and enables a fading signal when the voltage of the first terminal is higher than the reference voltage. When the trigger signal is enabled, the pulse generator outputs a pulse to control the switch element. When the fading signal is enabled, the pulse generator reduces a pulse width of the pulse.

    摘要: An induction heating cooker includes a switch element and an inductive coil, which is coupled between a power voltage and a first terminal of the switch element. A second terminal of the switch element is coupled to a common voltage. A control circuit for controlling the inducting heating cooker includes first and second comparators and a pulse generator. The first comparator receives voltages of two terminals of the inductive coil and thus outputs a trigger signal. The second comparator receives a reference voltage and a voltage of the first terminal of the switch element, and enables a fading signal when the voltage of the first terminal is higher than the reference voltage.
