通信电源无功补偿与谐波抑制方法研究

Research on Compensating Reactive and Harmonic of Communication Power Supply

本文系统阐述了用于通信电源无功补偿与谐波抑制的几种方法，在详细分析它们各自优、缺点 的基础上，提出了一种采用有源滤波的新颖设计思想，不仅能有效抑制通信电源产生的谐波污 染、补偿无功损耗，提高电源功率因数，同时，具有安全可靠性高、体积小和成本低的特点。

The ways normally compensating reactive and harmonic of communication power supply are gived in che paper.Based on the analysis of advantage and disadvantage of them. a new design using active power filter is provided.It is safe,stable,small and cheap.
