Embodiment Construction

[0024] figure 1 Shown is a structural block diagram of an embodiment of the unipolar microsecond pulse power supply of the present invention.

[0025] Such as figure 1 As shown, the present invention includes two parts, the main circuit system 110 and the control system 100 . The main circuit system 110 generates high-voltage direct current, and the control system 100 controls the switching on and off of the switches of the multi-stage power supply modules of the main circuit system to generate driving pulse signals required by high-voltage pulses. In the main circuit system 110, the AC power system and the AC voltage regulator charge the multi-stage power modules, and each single-stage power module discharges on the load matching resistance to obtain a unipolar microsecond pulse voltage, and the multi-stage low-voltage pulses are superimposed to obtain a single Polar microsecond pulse high voltage. In the control system 100, the output control pulse signal of the program-c...

Abstract

Provided is a unipolar microsecond pulse high voltage power supply. The unipolar microsecond pulse high voltage power supply comprises a main circuit system (110) and a control system (100). The main circuit system (110) finishes energy storing and charging of a power module of each stage, and the power module of each stage finishes discharging to load under the control of drive signals of the control system (100) and outputs unipolar microsecond pulse high voltage. The control system (100) generates level signals, the level signals are transmitted to a switch drive circuit of the main circuit system for generating drive control signals, so that connection and disconnection of a main circuit system switch is controlled, and pulse output is obtained at the tail end of the main circuit system. Low voltage pulses obtained by each single stage power module through discharging on a load matching resistor are added for obtaining high voltage pulses, the pulses of a plurality of stages are added synchronously so that square-wave pulses can be obtained, and then the work mode of the control system (100) is a synchronous trigger mode. Triangular waves with step edges can be obtained through delayed adding, and then the work mode of the control system (100) is a delayed trigger mode.

Description

technical field [0001] The invention relates to a pulse high-voltage power supply. Background technique [0002] Pulse high-voltage power supplies are widely used in military fields such as high-power particle beams, nuclear fusion, and particle accelerators, and in civilian fields such as biomedical engineering, material processing, three-waste treatment, nano-manufacturing, material processing, and ion implantation. High-voltage pulse power supply is a special power supply device through low-speed storage and high-speed release of energy. Through the opening and closing of various forms of switches and the cooperation of pulse shaping circuits, it outputs a high-voltage pulse generator with a certain width, amplitude and frequency. . With the continuous development of semiconductor switches and various magnetic materials, semiconductor switches and magnetic switches have been widely used in pulse power supplies. Compared with traditional gas switches, their advantages suc...
