PURPOSE: To provide an output compensating circuit of a high frequency induction heating cooker which can stably and accurately control the desired output power by compensating change in input voltage. CONSTITUTION: An output compensating circuit includes a voltage detecting part 10 detecting the voltage supplied to a working coil W/C so that it is in inverse proportion to change in input voltage, an output control part 120 generating output adjustment data through selection by the user, and a voltage distributing part 130 controlling the voltage level of the voltage detecting part 110 according to the output data of the output control part 120 and supplying the same as output adjustment voltage. Output power that is always stable irrespective of change in the input voltage of the working coil W/C can be obtained. |
