Journal: Transactions of China Electrotechnical Society

Keyword:  频域反卷积信号恢复空间电荷电场脉冲法;
Abstract: 电声脉冲法空间电荷测量系统的输出信号通常存在比较明显的过冲.本文分析了电声脉冲法空间电荷测量系统硬件结构造成信号畸变的原因,介绍了空间电荷测量信号恢复中反卷积处理技术及其问题.根据测量系统中高压脉冲及输出信号波形的特点,选取高斯滤波器对反卷积处理带来的病态问题进行了修正.基于上述改进设计了空间电荷测量信号恢复的频域反卷积算法,并采用LabVIEW实现了反卷积处理.通过实际对聚乙烯/纳米银复合材料空...
