摘要: 正 (一)引言 激光電光調(diào)制技術(shù)以及其它一些物理實(shí)驗(yàn)需要重復(fù)頻率高、電壓幅度高、寬度可變的快速高壓矩形脈沖發(fā)生器。根據(jù)需要,我們?cè)O(shè)計(jì)了雙臂式充放電電路。同時(shí)調(diào)試安裝了兩種規(guī)格的高壓脈沖發(fā)生器。 采用國產(chǎn)FM-30束射四極管作為高壓充放電管,達(dá)到的指標(biāo)如下: (1)脈沖幅度:最高5kV(250V5kV連續(xù)可調(diào),零電位為250V)。 (2)前后沿時(shí)間:負(fù)載電容為100pF時(shí),0.5s;負(fù)載電容為200pF時(shí),0.8s

Abstract: In this paper, a double arm charge-discharge circuit is described. A high repetition-rate high voltage and variable width rectangular pulse has been obtained. Its technical data are as follows: Its amplitude is 600 V-8 kV continuously adjustable; The maximum repetition-rate is 30kHz; The rise and fall time is less then 1.5s when the load capacity is 56 pF, less then 1.8s when the load capacity is 112 pF; The pulse duration ratio is 1:10-1:1 continuously adjustable. Theoretical analysis for the circuit, has been made. -
