摘　　要：提出了一种带有光伏发电的UPS系统,阐述了该系统的结构图。在分析双向变换器的拓扑结构、工作原理的基础上,采用基于前馈解耦控制的双环控制策略,实现整流逆变不同模式的自动切换以达到能量双向流动的目的。该方法具有输入电流无静差跟踪,对电网谐波污染少、功率因数高等优点。A UPS system with photovoltaic power generation has been proposed in this paper and the structure of the system has been stated in detail. On the basis of analyzing the bidirectional converter topology and working principle, a feedforward decoupling based double loop control strategy has been adopted to achieve the automatic switch in different modes of rectifier inverter as so to achieve a energy bi - direction flow. There is not any static error tracking input current,and the harmonic pollution is low as well as the power factor is high.
