PURPOSE: An apparatus for supplying a power to an induction heating cooker is provided to reduce size of a portion in which a power separation should be made inside a power supplying apparatus and reduce manufacturing cost of a product. CONSTITUTION: A power circuit supplies a high voltage to a working coil(120). A control circuit controls an operation of the power circuit part. A valve power supplying circuit supplies a power to a valve exposed to the outside of a product. A power separation circuit is electrically separated between the control circuit and the valve power supplying circuit and transmits a control signal of the control circuit. The power circuit and the control circuit are connected to the same ground electric potential. A power part including the working coil(120) and a power part of a micro computer(155) for performing a control of the system are connected to the same power source part. The power of the solenoid valve(160) for discharging vapor is separated in terms of a power source. Thus, a portion in which the power separation should be performed inside the control circuit of the product is constructed to become small as possible as it could be.
