Title: INDUCTION HEATING COOKER POWER CONTROL CIRCUIT
Abstract:
The present invention relates to a power control circuit (1) that is suitable to be used in induction heating cookers and that provides the generation of magnetic energy for heating a vessel (14) placed onto the induction heating cooker surface, comprising a bridge rectifier (2) that converts the alternative current received from the mains into direct current; a filter inductor (3) and a filter capacitor (4) that are disposed at the outlet of the bridge rectifier (2); an induction coil (5); at least one resonant capacitor (6); at least one power switch (7); a drive circuit (8), and a microcontroller (9) that regulates the operation of the power switch (7) by means of the drive circuit (8), whereon the power control circuit (1) detects the presence of the vessel (14) on the induction heating cooker.
