High-repetition-frequency fast pulse generation circuit and method based on preceding-stage pre-triggering

The invention discloses a high repetition frequency fast pulse generation circuit and method based on preceding stage pre-triggering, the pulse generation circuit comprises a Marx circuit composed of a plurality of stages of charging capacitors, power switches are arranged among the stages of charging capacitors, two groups of isolation resistors and isolation magnetic beads are arranged on a loop of each stage of charging capacitor, the first stage is an external triggering stage, and the second stage is an external triggering stage. The power switch is controlled after being steepened by the trigger circuit through an external input pulse, the pre-stage circuit is a pre-trigger stage, the intermediate stage is a collector overvoltage conduction stage, and the final stage is a load unit. The pulse generation circuit can effectively reduce the heating phenomenon of the preceding-stage avalanche transistor and improve the pulse source repetition frequency upper limit. 本发明公开一种基于前级预触发的高重频快脉冲产生电路及方法，脉冲产生电路包括若干级充电
