A microwave heating apparatus (100) and a method of operating a microwave heating apparatus are provided. The microwave heating apparatus comprises a microwave source (110) for generating microwaves, a transmission line (120) for transmitting the generated microwaves from the microwave source to a cavity (130), measuring means (140) for measuring the power of microwaves transmitted from the microwave source and receiving means (150) for receiving operational data indicative of the power supplied to the microwave source. The microwave heating apparatus further comprises a control unit (170) adapted to adjust the impedance of the transmission line and/or the impedance matching between the microwave source and the transmission line based on the measured power of the transmitted microwaves and the received operational data in order to control the efficiency of the microwave source. The present invention is advantageous in that the microwave heating apparatus is operated with an improved control of the microwave source efficiency. |
