The　theory　of　magnetic　pulse　compression　is　applied　to　the　design　of　a　high-voltage　pulse　generator　to　generate　high-voltage　pulse　with　nanosecond　and　high-steepness　leading　edge.　CLC　resonance　is　made　use　of　to　produce　resonant　voltage,　and　the　magnetic　switch　parameters　are　designed　according　to　the　principle　of　magnetic　pulse　compression.　And　the　influence　of　diode　on　the　output　voltage　waveform　and　the　impact　of　capacitor　parameters　on　the　output　energy　are　analyzed.　Simulation　results　show　that　the　generator　can　more　effectively　produce　plasma　when　the　continuous　high-voltage　pulse　is　of　the　11.06　kV　in　voltage　peak　value　measured　on　equivalent　load,　20　ns　in　the　rise　time　of　waveform,　0.611　J　in　the　maximum　energy　and　1　000　Hz　in　the　frequency.　©　2017,　Xi＇an　High　Voltage　Apparatus　Research　Institute　Co.,　Ltd.　All　right　reserved.
