摘要
介绍利用高频小功率晶体管的雪崩效应设计激光器的大电流窄脉冲驱动电路 ,对该电路建立了数学模型 ,并对电路参数进行了仿真。实验制作了产生宽度约为 10 ns,峰值约 2 0 A的脉冲驱动电路。仿真结果与实验相吻合 ,因此 ,对实际应用有一定的指导意义。
This paper introduces a kind of large current and narrow width pulsed driving circuit which is based on the avalanche effect of high freguency and small power transistors.Such circuit outputs current impulses of 10 ns wide and 20 A high.A mathematical model of the circuit is created and emulated.The result of emulation coincides with the experiment.
