Description

technical field [0001] The invention relates to a matrix converter control technology, in particular to an AC-DC series resonant matrix converter control device for capacitor charging and a control method thereof. Background technique [0002] In order to meet the military needs of future high-tech warfare, high-power microwave systems are developing in the direction of high power, miniaturization, and light weight. Higher requirements are imposed, among which, the capacitor charging power supply is a more common choice in high-power microwave systems. [0003] At present, the capacitor charging power supply used in high-power microwave systems generally adopts DC-Link technology with an intermediate DC energy storage link. Although the intermediate energy storage link has the advantages of large capacity and long life, its existence will increase the power system. The volume and weight reduce the power density of the power supply, and the power quality of this power supply...
