摘要： 針對電感隔離型重頻Marx發(fā)生器的充電需求，研制了一臺猝發(fā)重頻高壓大功率脈沖充電電源。該電源采用直流電源+儲能電容+晶閘管開關(guān)+脈沖變壓器的技術(shù)路線，設(shè)計指標為充電電壓為90 kV，充電電流1 kA，充電重復(fù)頻率1 Hz～100 Hz可調(diào)，猝發(fā)工作時最大充電次數(shù)為5次。首先介紹了充電電源的工作原理，進行了電路參數(shù)計算和結(jié)構(gòu)設(shè)計，得到了晶閘管、初級電源和脈沖變壓器等主要器件的參數(shù)。然后試制組裝了一套電源，并進行了實驗驗證：對等效總電容量為0.7 μF的緊湊型Marx發(fā)生器充電時，充電電壓90 kV，充電時間小于120 μs，充電重復(fù)頻率10 Hz。該電源的研制成功對高功率重復(fù)頻率脈沖功率源的進一步小型化具有重要意義。

Abstract： In order to meet the charging requirements of the repetitive pulse power source based on inductance isolated Marx generator, a burst repetitive high-voltage and high-power pulse charging power supply was designed and developed. The power supply adopts the pulse transformer technology route, with a designed charging voltage of 90 kV, charging current of 1 kA, adjustable charging repetition frequency of 1~100 Hz, and a maximum burst charging frequency of 5 times. This article introduces the working principle of charging power supply, conducts circuit parameter calculation and structural design, and obtains the parameters of main components such as thyristors, primary power supply, and pulse transformers. This power supply charges a compact Marx generator with an equivalent total capacitance of 0.7 μF, achieving a charging voltage of 90 kV, a charging time of less than 120 μs， and technical specifications for charging repetition frequency of 10 Hz. The development of this power supply has reference significance for further miniaturization research of high-power repetitive pulse power sources.

引言
脈沖功率技術(shù)是近幾十年內(nèi)快速發(fā)展起來的一門新興科學，隨后在高功率微波、強激光、電磁發(fā)射等國防軍事需求及民用領(lǐng)域日益廣泛應(yīng)用的牽引下，取得了巨大進步[1-3]。重復(fù)頻率、小型化是脈沖功率源重要的發(fā)展方向之一，基于電容儲能電感隔離的Marx發(fā)生器工作頻率不斷提高[4-8]。為了滿足儲能電容快速充電的需求，本文設(shè)計并研制了一臺猝發(fā)重頻高壓大功率脈沖充電電源，利用交流220 V供電，實現(xiàn)輸出電壓大于90 kV脈沖電流大于1 kA，充電峰值功率大于30 MW，可猝發(fā)5脈沖重頻輸出，重復(fù)頻率1~100 Hz可調(diào)。
