Description

technical field [0001] The invention relates to the technical field of industrial power supplies, in particular to a digital magnetron power supply. Background technique [0002] Microwave heating has the advantages of uniform heating, fast speed, high thermal efficiency, and easy automatic control. Compared with traditional heating technology, microwave heating undoubtedly has great attractiveness and broad industrial application prospects. The core component of microwave power equipment is the switching power supply that drives the microwave source, and its working efficiency and stability directly affect the overall performance of microwave equipment. [0003] There are two types of traditional magnetron driving power supply, one is linear power supply and the other is pulse driving power supply; the linear power supply uses a voltage doubler circuit composed of a power frequency transformer, diodes, and capacitors to generate anode high voltage. This structure uses a p...
