摘要

将由电源滤波器、压敏电阻、瞬态电压抑制器（TVS）组成的串级浪涌抑制网络应用于智能电器监控单元电源端口

通过试验观察到该网络的残压水平过高

对后级电路存在着潜在的危险

采用波过程理论对这一现象进行分析

发现开关电源阻抗变化会影响到串级浪涌抑制网络的配合。对抑制网络的结构进行了改进

通过试验可以证明改进后的抑制网络能够明显提高对浪涌过电压的抑制效果。

Abstract

The serial surge suppresses net which was constituted with mains filter

varistor and transient voltage suppressor was applied to the power supply port.The over-high residual voltage and potential danger to posterior circuit were found by experiment.Through analyzing experiment phenomena by using the traveling wave theory

it was found that coordination of the depress net was influenced by variation of resistance of switch power.The structure of suppress net was redesigned and it was proved that the new structure can improve suppress result obviously by experiment.
