Induction heat cooking apparatus and method for driving the same

An electronic induction heat cooking apparatus comprising:

• a rectifier including a bridge diode, the rectifier being configured to rectify an input voltage and to output a direct current (DC) voltage;
• a plurality of switching elements configured to switch the DC voltage output through the rectifier;
• a controller configured to control the plurality of switching elements;
• a plurality of heating coils configured to heat a cooking utensil by controlling the plurality of switching elements;
• a cooling fan configured to cool the plurality of switching elements;
• a heat sink having the plurality of switching elements mounted thereon, the heat sink being configured to cool the plurality of switching elements;
• a cover that covers the plurality of switching elements;
• coupling members that couple the heat sink to the cover;
• and
• a radiation fin that is configured to cool the plurality of switching elements and that is disposed on the cover,
• wherein the plurality of switching elements and the bridge diode are mounted on a mounting surface of the heat sink,
• wherein the plurality of switching elements are arranged at a central region of the mounting surface,
• wherein the bridge diode is disposed outside the central region of the mounting surface, and
• wherein the cooling fan is disposed at a position closer to the bridge diode than to the plurality of switching elements, and
• wherein the cover extends along a length direction of the cover to cover and covers all of the plurality of switching elements and the bridge diode.
