摘要
从概念原理、主电路结构、检测方法、控制策略等方面对应用APF(有源电力滤波器)技术的新型在线互动式UPS(不间断电源)进行了介绍。经过相关具体电路分析发现,应用APF技术的新型在线互动式UPS具有多种功能,可以用来低成本的消除UPS和负载对电力系统产生的谐波,同时也可以消除电力系统和其他负载对用户干扰。
A new type on line interactive UPS(Uninterrupted power source)applying APF(Active power filter)technique is introduced from the respects of conceptional principles,structure of main circuit,detection method and control policy.Through the analysis on relative specific circuit,it is discovered that,such new type on line interactive UPS possesses many kinds of function,it can eliminate the harmonics in power system produced by UPS and its loads with low costs,at same time it also can eliminate the interferences to users produced by power system and other loads.
