| 摘 要： | 设计了一种用于测量脉冲高电压的电阻分压器。通过FEKO电磁仿真计算软件计算输出端的电压波形，分析其特性。对典型结构模型的仿真分析表明，分压器两端采用过渡结构，可以减小由于阻抗失配引起的反射，明显改善输出端波形。对直线型、凸型或凹型过渡的对比分析表明，直线型过渡具有优势。实验测试表明，该分压器性能优越，满足高压纳秒双指数脉冲的测量要求，试验波形光滑，未见明显反射。

| Abstract: | A compact resistance divider is introduced,which is used for measuring high-voltage pulse. This article used electromagnetic simulation software FEKO to calculate the output voltage waveform. In the paper,it analyzed the divider's characteristics and adjusted the structural parameters. Through the simulation analysis of typical structural model analysis,it showed that the divider which ends used the transition structure can reduce the reflections caused by impedance mismatch,also made the significant improv... |
