摘要
介绍了双变流器串-并联补偿式UPS的组成和特点,进而分析了串联变换器的工作原理及其在UPS系统中的重要作用。同时考虑了理想电压和非理想电压下串联变换器的控制策略,最后通过仿真结果的分析,验证了控制方案的可行性。
This paper presents the construction and characters of the series-parallel compensated UPS,and analyses the principle and important functions in the whole UPS system.It also takes into account the control strategy of series converter in the event of the ideal voltage and non-ideal voltage.In the end,from the simulation results of the load voltage and current,this paper proves the feasibility of the control strategy.
