利用传统方法实现高重频高压窄脉冲源受制于的器件性能,因而提出了频率叠加的新思路。基于超快电子学和频率叠加理论,利用MARX电路产生多路高压窄脉冲,通过同步系统控制多路触发信号延时,使多路脉冲耦合成一路输出,实现高重频高压窄脉冲输出。实验中两个单路高压窄脉冲的幅度为2.56 kV,宽度为7.13 ns,重复频率为32 kHz,两路脉冲耦合后,输出脉冲幅度为2.46 kV,宽度为7.49 ns,重复频率为64 kHz。该实验验证了设计思路的可行性,实现了输出脉冲重复频率倍增。该方法可以推广至更多路脉冲的频率叠加,获得更高频率。
The traditional method is used to realize the device performance controlled by high repetition frequency and high voltage narrow pulse source. Therefore, a new idea of frequency superposition is put forward. Based on the theory of ultrafast electronics and frequency superposition, a multi-channel high-voltage narrow pulse is generated by the MARX circuit, and the multi-channel trigger signal is controlled by the synchronization system to delay the delay so as to couple the multi-channel pulses into one output for high repetition and high voltage narrow pulse output. In the experiment, the amplitudes of two single high-voltage narrow pulses are 2.56 kV, the width is 7.13 ns and the repetition frequency is 32 kHz. After the two pulses are coupled, the output pulse amplitude is 2.46 kV, the width is 7.49 ns and the repetition frequency is 64 kHz. The experimental verification of the feasibility of the design ideas, to achieve the output pulse repetition frequency multiplication. The method can be extended to more pulse superimposed frequency, to obtain higher frequencies.
