带截尾开关的高频纳秒脉冲功率源设计
Design on High-frequency Nanosecond Pulse Power Source with Truncated Switches
摘要
Abstract
In order to obtain a high-frequency nanosecond pulse with a fast rising and falling edge,the traditional avalanche single-tube pulse circuit was tested and the feasibility of this circuit was verified to speed up the charging speed.Designing two ten-stage nanosecond Marx type generator with positive pulse,the driving scheme of generator was that magnetic rings were used to isolate,in the topological structure of the main circuit,diodes were used to instead of all resistors which were used in traditional Marx circuit.The discharge experiment was carried out under a resistive load of 100 Ω.Finally,the output voltage of the high-repetition nanosecond pulse reaching 1 kV,the output of the load in parallel truncated switches could further shorten the falling edge of the output pulse to 3ns.The experimental results show that the improved generator has higher output amplitude and operating frequency,the driving scheme of generator is using magnetic rings to isolate,thus ensures each avalanche transistors to trigger simultaneously and produce fast pulse with nanosecond rising edge.Diodes which are used to replace all resistors have accelerated the charging speed and improved the working efficiency of the pulse generator,the falling edge is faster when the output of the load in parallel truncated switches,the experimental results are good.关键词
