Abstract

The invention discloses a control device and a control method for an AC-DC (Alternating Current-Direct Current) series resonant matrix converter for capacitor charging and mainly aims at solving the problem in the prior art that the control property of a capacitor charging power supply is not high enough to meet the power supply requirement of a high-power microwave system. The control device for the AC-DC (Alternating Current-Direct Current) series resonant matrix converter for capacitor charging comprises a zero-crossing comparator, an On-Off state control unit, a timing sequence generating unit, a control parameter calculation unit, a load voltage acquisition circuit and a trigger driving circuit. The invention further discloses a control method of the control device. With the technical scheme, the control device and the control method, disclosed by the invention, have the advantages that the price/performance ratio is relatively high property, the power supply requirement of the high-power microwave system can be sufficiently met, and the practical value and the popularization value are high.

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...
