Abstract
A microwave heating system includes: a power supply; a first semiconductor module configured to receive power from the power supply and to generate a first microwave; a second semiconductor module configured to receive power from the power supply and to generate a second microwave; a heating chamber that is configured to accommodate an object at an inside of the heating chamber and that allows transmission of the first microwave and the second microwave to the inside of the heating chamber; and a control unit. The control unit is configured to control operation of each of the first semiconductor module and the second semiconductor module, and to control at least one of a frequency, a phase, or a magnitude of each of the first microwave and the second microwave to increase a heating uniformity of the object.
