中文摘要：

分析LC滤波器在整流电路交流侧时瞬态过程的浪涌电压,将滤波器中的电感移到整流器的交流侧可以克服铁芯直流磁化和易饱和的缺点。这并不会影响滤波器稳态过程的外特征,但是瞬态过程会发生变化。瞬态分析是电路分析的难点,瞬态过程是故障发生的高概率区间,其中浪涌电压是对设备安全有着很大影响的重要参数。提出一种改进的五维可视化的方法,分析整流器上电的瞬间LC滤波器瞬态过程的外特征,得出了浪涌电压在初始阶段变化的可视化图形,为电路分析提供了一种新的可视化分析方法。

英文摘要：

The purpose of this study is to analyze the surge voltage of uncontrolled single-phase rectifier with LC filter,when the inductor is located in the AC side of the rectifier bridge. The DC inductor was easier to be magnetized and saturated than AC inductor which has the same external characteristic in steady state but different in transient. It is very difficult to analyze the transient,but the surge voltage is a very important parameter which may be lead to fault of some element. This paper presented an improved five-dimensional visualization to analyze surge voltage of AC inductor,the result of visualization proves this method that is useful and effective.
