摘　　要：脉冲成形网络通过对储能元件缓慢充电并迅速放电从而得到各种陡前沿脉冲，为了提高脉冲成形网络的性能，必须对其与性能相关的技术参数进行测量。通过对脉冲电容器充放电特性测量中的3种高压分压器——电阻式、电容式和阻容式进行比较研究，在分析其结构组成及工作原理的基础上，根据实验要求设计3种分压器并分别用于对高压脉冲电容器充放电特性测量，实验波形分析结果表明，在测量脉冲电容器充电和短路放电电压实验时，电阻式分压器优于其它两种分压器。Pulse forming network （PFN） can get all kinds of steep front impulse through charging slowly and discharging rapidly energy storage component. In order to improve the performance of PFN, the technical parameters that performance related must be measured. A comparative study is conducted on the three kinds of high-vohage divider resistive, capacitive and capacitive resistor in pulse capacitor charge-discharge characteristics measurement. First of all, simulation study is carried out using Simulink software based on the analysis of its structure and operation principle, and then the three kinds of dividers are designed according to experimental demands, which are used for the charge-discharge characteristics measurement of high-voltage pulse divider capacitor separately. Simulation waveforms are compared to experimental waveforms, analysis results show that the resistive divider is better than the other two kinds of voltage dividers during measurement of pulse capacitor charge and short-circuit discharge voltage experiment.
