Abstract

The invention discloses a high-voltage and high-power repetitive pulse power supply, which comprises a charging power supply, an energy-storing capacitor group, a residual voltage processing branch circuit and an energy feedback branch circuit, wherein the energy-storing capacitor group comprises a primary capacitor C1 and a secondary capacitor C2 which are connected in series and have the same capacitance and opposite polarity directions; the energy feedback branch circuit is connected in parallel with the energy-storing capacitor group; the residual voltage processing branch circuit is connected in parallel to the two ends of the secondary capacitor C2 respectively; and the charging power supply is connected in parallel to the two ends of the primary capacitor C1. In the high-voltage and high-power repetitive pulse power supply, a dual-capacitor energy saving and discharging way is adopted, so that the primary capacitor is free from back voltage, the secondary capacitor is free from back voltage or only bears the back voltage below 10 percent, and reliability of a unipolar capacitor is enhanced, the working service life of the unipolar capacitor is prolonged, and the working frequency of a system is increased; and the high-voltage and high-power repetitive pulse power supply is a novel compact repetitive pulse power supply based on dual-capacitor discharging, resonant mode energy feedback and energy-storing capacitor residual voltage processing.

Description

technical field [0001] The invention belongs to the pulse power technology, specifically relates to a power supply of a high-voltage high-power repetitive pulse power system suitable for inductive loads in the pulse power technology, and particularly relates to the topology structure of the power supply of the repetitive pulse power system. Background technique [0002] Repetitive pulse power technology has important applications in scientific research and national defense industry, and is an important direction for the development of pulse power technology. Generating repetitive pulse power requires a matching high-voltage high-power repetitive pulse power supply, and the repetition frequency, capacity, pulse width and reliability of the power supply must meet certain requirements. [0003] The load of repetitive pulse power supply is mainly divided into three categories: resistive load, capacitive load and inductive load. Among them, the inductive load type repetitive pul...
