摘 要：介绍了一种改善大电容负载的雷电冲击电压试验输出波形的方法，分析了容性负载时雷电冲击电压波形振荡和过冲的原因，指出了调试雷电冲击电压波形常用的措施，并在冲击电压试验回路中串联RLC滤波电路来对现用低通滤波电路进行改进。仿真分析表明，改进后的RLC低通滤波电路比原先的RC低通滤波电路的波形平滑度好，雷电冲击电压波形波头振荡得到明显改善。

Abstract: Introduction was made to a method improving the output waveform of lightning impulse voltage test for large capacitive loads. This paper analyzed the reason of lightning impulse voltage waveform oscillation and overshoot under capacitive load. The common measures were used to debug lightning impulse voltage waveform and the existing low-pass filter circuit was improved by the way of series RLC filter circuit in impulse voltage test circuit. The simulation result shows that the waveform of the improved RLC low-pass filter circuit is smoother than the waveform of the original circuit. The lightning impulse voltage waveform oscillation has been improved obviously.
Key words: lightning impulse voltage waveform; large capacitive load; waveform overshoot; RLC filter circuit
