在线式UPS数字化复合控制技术的研究

Study of Digital Compound-control Technology of On-line UPS

分析了目前用于不间断电源(UPS)逆变控制的几种方法的优缺点,指出复合型控制策略将是在线式UPS逆变器控制策略的发展方向。提出一种基于TMS320LF2407型DS的复合型控制策略设计方案,并对系统进行了实验验证。实验结果证明了该系统的可行性和先进性。

The on-line UPS is introduced briefly.The paper analyzes the advantages and disadvantages of many important methods used in UPS＇s inverter control, and proposes that the tendency of the inverter control strategies is compoundcontrol.Finally,a compound-control scheme based on DSP/TMS320LF2407 is proposed,and this system is tested.The experimental results verify the system＇s feasibility and advantage.
