INDUTION HEATING COOKTOP WITH A SINGLE INVERTER AND CONTROL METHOD THEREOF

摘要

PURPOSE: An induction heating electric cooker equipped with a single inverter is provided to prevent the generation of noise due to the difference of frequencies in the state of supplying high frequency current to more than two heating coils by using single inverter. CONSTITUTION: A power supply unit(20) changes the AC power source into the DC power source. One inverter unit(30) offers the AC voltage by switching the DC power source. A plurality of heating units(100, 200) is supplied with the current of the high frequency by the AC voltage. The heating units heat the cooking container by inducing the eddy current.
