摘要
串并联补偿式在线UPS和其他型式的UPS相比具有许多优点,但也存在一些不足之处。在分析现有串并联变换型UPS系统电路结构的基础上,指出了其在市电停电时存在输出效率不高以及开关损耗大等问题,并提出了一种新型的UPS系统模型,对新型UPS的工作原理进行了详细地分析。在MATLAB6.5版的Simulink环境中,对新型的UPS进行了仿真研究,仿真结果表明新型UPS系统在满足用电设备的要求下,降低了开关损耗,提高了系统的整体效率,从而改善了UPS系统的性能。
Series-parallel compensated UPS has many unexampled merits compared with the other types of UPS, but also has some shortages. The paper points out some shortages such as low output efficiency and great wastage of switch when power cut based on the analysis of circuit structure of existing series-parallel converted LIPS, and brings forward a new type UPS model, analyzes the operation principle of the new type UPS in detail. Some simulating research was done to the new type UPS in the Simulink condition of MATLAB6.5, the simulating results indicate the new type UPS can satisfy electric equipments, reduce the wastage of switch, enhance the whole efficiency of system, consequently improved the capability of UPS.
