摘要

本文提出了一种新的三相串并联互动式不间断电源拓扑结构。新的拓扑结构具有较少的电力电子器件数量和控制功能。大部分电力直接从交流线路提供给负载。因此，整体效率高于在线UPS。并对系统的不同工作模式以及串、并联变流器进行了研究。仿真和实验结果表明了所提拓扑的可行性。

Reduced parts three-phase series-parallel UPS system with active filter capabilities

In this paper, a new three-phase series-parallel line-interactive uninterruptible power supply (UPS) topology is presented. The new topology has less number of power electronic devices as well as control functions. Most of the power is supplied directly from the AC line to the load. Therefore, the overall efficiency is higher than that of on-line UPS. Different operating modes of the system and series and parallel converters are investigated as well. Simulation and experimental results are presented, which show the viability of the proposed topology.
