Disclosed are a microwave power source and a method of adjusting operation frequency for a microwave oven. The microwave power source comprises: a phase-locked frequency generator configured to generate a plurality of operation frequencies; a standing wave detection circuit configured to detect, for each operation frequency, a standing wave in a chamber of the oven and provide information about the standing wave; and a microcontroller configured to select one of the operation frequencies based on the information, and control the generator to generate the selected operation frequency so that the microwave oven operates at the selected operation frequency. Embodiments of the present disclosure can automatically adjust the operation frequency of the oven according to VSWR in the oven chamber. |
