Abstract: 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.

Abstract: The present invention relates to a programmable frequency divider having one n-bit adder and one n-bit D Flip Flop. These are used to transform the import clock to the target clock. The adder takes one adjustment parameter and one return signal as a basis to create the first output signal, with the possibility to program the adjustment parameter. The D Flip Flop and the adder create a cycle, which is used to receive the first output signal and its import clock to create the second output signal. The second output signal is separated into a return signal and the target signal. The D Flip Flop sends the return signal back to the adder, which will make addition calculations under the adjustment parameter, finally giving out the target clock with the target signal as a calculation basis.
