Abstract
An electronic induction heat cooking apparatus includes a rectifier including a bridge diode, for rectifying an input voltage and outputting a direct current (DC) voltage; a plurality of switching elements for switching the DC voltage output through the rectifier; a controller for controlling the plurality of switching elements; a plurality of heating coils for heating a cooking utensil by controlling the plurality of switching elements; a heat sink having the plurality of switching elements mounted thereon, for cooling the plurality of switching elements; a cover covering the plurality of switching elements; and coupling members for coupling the heat sink to the cover. A radiation fin for cooling the plurality of switching elements is formed on the cover.
