【摘要】 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效率不高以及开关损耗大等问题,提出一种新型UPS系统模型,对新型UPS工作原理进行了详细的分析。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。更多还原

【Abstract】 Based on analyzing the existing series- parallel converted UPS,a new UPS system model is proposed and its principle is described in detail. The proposed UPS system is simulated using the Simulink of Matlab6.5. The simulation result has shown that the proposed UPS system can reduce the wastage of switch and enhance the whole efficiency of system under condition of satisfying electric equipments’demand. Accordingly,the new UPS system outperforms the existing UPS system.更多还原
