Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0023] In the 1980s, I.V.Grekhov, an academician of the former Soviet Union, and others proposed a new switching principle with the help of a controllable plasma layer, and invented a reversely switched transistor (Reversely Switched Dynistor, RSD) device on this basis. The RSD device is a device composed of tens of thousands of thyristors and transistor cells arranged in parallel with each othe...

Abstract

The invention discloses a charging source for a high-voltage capacitor. The charging source comprises a low-voltage rectifying circuit, a bridge type inverter circuit, a resonance circuit, a boosting transformer and a high-voltage rectifying circuit, wherein the low-voltage rectifying circuit is used for performing AC/DC conversion on alternating current to output direct current voltage; the bridge type inverter circuit and the resonance circuit are used for performing resonant conversion on the direct current voltage to output bipolar voltage pulse; the boosting transformer and the high-voltage rectifying circuit are used for converting the bipolar voltage pulse into unipolar voltage pulse to charge the high-voltage capacitor; the bridge type inverter circuit consists of RSD (removable storage device) switch units; and each RSD switch unit comprises an RSD heap, a reverse pick-off diode, a reverse protection diode, a first saturable magnetic switch and an RSD pre-charging circuit, and the RSD heap is formed through series connection and/or parallel connection of one or more RSD devices. The charging source for the high-voltage capacitor can effectively improve the charging efficiency of the high-voltage capacitor, shortens the charging time, and is small in size and low in cost.
