摘　　要：速调管需要脉冲功率来产生高功率微波,但是由于线路寄生参数、储能电容容量与负载大小等因素会使输出脉冲波形产生顶降,为补偿固态脉冲电源的输出顶降,设计了基于LC并联谐振的补偿模块。选用DSP作为控制芯片产生三路驱动信号控制开关管,将谐振余弦电压的上升部分与输出脉冲电压叠加,对输出电压顶降进行补偿。研制了一种带有补偿电路的Marx发生器。实验表明,在负载为5Ω、重复频率为100 Hz时,输出脉冲电压幅度为1.4 kV的顶降由10%降低到3%,提高了输出脉冲顶部平坦度与脉冲波形质量。The klystron needs pulse power to generate high power microwave,but the output pulse waveform will drop due to factors such as line parasitic parameters,energy storage capacitor capacity and load size.In order to compensate the output drop of the solid-state pulse power supply,a compensation module based on LC parallel resonance is designed.DSP is selected as the control chip to generate three-way sequential control switch tube,and the rising part of the resonant cosine voltage is superimposed with the output pulse voltage to compensate the output voltage drop.A Marx generator with compensation circuit is developed.Experiments show that when the load is 5Ωand the repetition frequency is 100 Hz,the top drop of the output pulse voltage amplitude of 1.4 kV is compensated from 10%to 3%,which improves the top flatness of the output pulse and the quality of the pulse waveform.
