【摘要】 基于雪崩三极管的脉冲源具有稳定度高、脉冲窄、上升时间短等优点,分析了雪崩三极管脉冲源稳定度的影响因素。采用适当的优化措施提高了稳定度指标,设计了高稳定度的雪崩三极管脉冲源,脉冲峰值电压1500V(50Ω负载),脉冲宽度1ns,上升时间200ps,具有很高的稳定度指标:短时抖动小于30ps,长时漂移小于100ps/min,峰值电压和脉冲宽度抖动小于1%。通过对改进脉冲电路的充电形式,实现了重复频率为60kHz的脉冲输出。更多还原

【Abstract】 The merits of the full-solid-state pulser,based on avalanche transistor,are high stability,narrow pulse and short rise-time.In this paper,the effect factors of the stability are analyzed.Some optimizing measures are used to improve the stability,and a high-stability pulser is designed:peak voltage is 1 500 V,pulse width is 1 ns,and the pulse width jitter is less than 1% and the peak voltage jitter is less than 1%.By improving the charging form of pulse circuit,the output pulse with repetition of 60 kHz is realized.更多还原
