Design Of A New Sort Of High-powered Pulsed Power Supply

With the uninterruptedly development of pulsed power technology, the application of pulsed power technology in both of national defence and national produce have been more and more abroad. To be the major constitute part of pulsed power technology, high-powered pulsed power supply has been got more and more attention by people. Higher power and higher repetition rate are all along the develop direction of high-powered pulsed power supply.This paper introduced the design, install and debug of a new sort of high-powered pulsed power supply. The power supply is composed of several parts as: harmonic suppressing circuit, resonance charging circuit, energy retrieving circuit, energy discharging circuit and computer control unit. The main parameter are: the mean power of 150kW, the highest output voltage of 500V, the maximun output current of 150kA, the capacity emit energy of 1350J every period, the maximun repetitive rate of 1~100 Hz.This system work process is composed by such actions: primary charging, discharging of the pulse capacitor, the gas- switch turning on, energy retrieving and resonance charging. Each work process of this system was controlled by long-distance computer. The control software of this system was wroten by LabVIEW of the NI Co.After debugging the system, it can work stabilize under the repetitive of 1~ 100 Hz, which totally meets the requirements of the accelerator. In addition, all parts of this pulsed power supply are made in china. Such as big current celerity crystal dust, repetition rate small inductance capacitor and resonance inductance are consigned correlation factory and academe to develop. Thereby, it can also improve the domestic produce ability of these parts of an apparatus. The pulsed power can works by high output voltage and large output current under the repetition rates, it has some merits: simple structure, high efficiency and high reliability. The repetition pulse power supply not only has been used in accelerator, but also can be applied in other pulse power technology fields.
