摘要
本文分析了计算机开关电源的特点及原理。论述了开关电源对电网产生干扰的原因及其危害。并联系实际提出了抑制干扰的三种有效措施:进线端接EMI滤波器、采用有源功率因数校正(APFC)装置、加接吸收电路。理论和实践证明是有效和可行的。
The traits and theory of the computer switch-power supply are analyzed in this article. The reasons, which the switch-power supply may make disturbance on electric network and their harms are discussed. Three effective measures, such as linking EMI filters to inlet, using APFC sets and imbibing circuits were set forth to suppress disturbance practically. It indicates effectively in theory and in practice.
