Title:
INDUCTION HEATING COOKER POWER CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/149055
Kind Code:
A1
Abstract:
The present invention relates to a power control circuit (1) suitable to be used in induction heating cookers, comprising an AC filter circuit (2) that filters the mains current; a bridge rectifier (3) that converts the alternative current received from the mains into direct current; a DC filter inductor (4) and a DC filter capacitor (5) that are disposed at the outlet of the bridge rectifier (3) on the DC line; an induction coil (6) that is energized for heating the vessel (16) placed onto the induction heating cooker; at least one resonant capacitor (7) that energizes the induction coil (6); at least one power switch (8), for example an IGBT (Insulated Gate Bipolar Transistor) that enables the resonant capacitor (7) to be charged/discharged and that provides the transmission of power from the induction coil (6) to the vessel (16); a drive voltage (9) that enables the power switch (8) to be driven with a drive voltage at the desired level; a collector node (10) whereon the resonant voltage is generated, and a microcontroller (11) that regulates the operation of the power switch (8) by means of the drive circuit (9), the power control circuit (1) determining whether or not the ferromagnetic characteristics of the vessel (16) placed on the induction coil (6) are suitable for induction heating.
