| 摘 要： | 提出了用磁芯电感器与穿心电容器相结合的尖脉冲干扰滤波器设计方案.论述了磁芯电感器滤波原理,给出并分析了该滤波器设计中的关键问题:采用LC滤波器,其中L为分布电容可以忽略的高磁导率磁芯电感器,C为寄生电感很小的穿心电容器;尖脉冲干扰滤波器放在低压电源滤波电解电容器之后;选择无气隙环形高磁导率铁氧体材料的磁芯;按所提出的计算方法确定线圈匝数和磁芯截面积.该方案能保证所设计的滤波器是经济、实用的.

| Abstract: | The design of a sharp pulse disturbance filter is proposed,which combines the magnetic core inductor with the feed-through capacitor.The working principle of the magnetic core inductor filter is described and the key techniques applied in filter design are given:LC filter is used,where L is a magnetic core inductor with high magnetic permeability and negligible distributive capacitance,C is a feed-through capacitor with little parasitic inductance;the filter is placed after the electrolytic capacitor of the... |
