Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a microwave generating device, a microwave heating device and a heating method. Background technique [0002] With the continuous development of science and technology, the application fields of microwave are becoming more and more extensive. For example, the microwave ovens used in people's daily life utilize microwaves to heat food. [0003] The premise of using microwaves is the need to construct a specific microwave source, that is, to generate specific microwaves as needed. In traditional methods, a magnetron is usually used to generate specific microwaves. The microwave generating device based on the magnetron includes a power supply, a magnetron, a control circuit, a resonant cavity and the like. The power supply outputs voltage to the magnetron, and the magnetron oscillates to generate microwaves, which then output microwaves through the waveguide system. [0004]...
