ABSTRACT:
An inverter rectifies an AC input to produce a DC output and switches the DC output so as to selectively obtain a high-frequency output for microwave or induction heating. A microwave heating unit is coupled to the inverter, receives the high-frequency output for microwave heating, and generates a first heating power of a microwave. An induction heating unit is coupled to the inverter, receives the high-frequency output for induction heating, and generates a second heating power of electromagnetic induction. An output setting unit selectively sets an output setting value for the first or second heating power. An input detector detects a current value of the AC input to the inverter. A controller compares the output setting value from the output setting section with the current value from the input detector, outputs a control signal representing the comparison result to the inverter so as to control the output from the inverter, and causes the microwave heating unit or induction heating unit to selectively generate the first or second heating power.
