Document Type and Number:
WIPO Patent Application WO/2023/022283
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide an induction heating type cooktop which minimizes the formation of negative voltage and the occurrence of ringing in an inverter employing a wide band gap (WBG) element. The induction heating type cooktop comprises: a top plate glass on which a cooking vessel is placed; a working coil which generates a magnetic field for heating the cooking vessel; and an inverter which includes at least one switching element operated to allow a current to flow though the working coil and a driving unit configured to drive the switching element, wherein the driving unit has a variable combined impedance.
