摘　　要：相比较蓄电池而言,在线式UPS是通过逆变器直接给负载供电。逆变输出电能质量的好坏会对负载的工作造成很大的影响。采用双闭环PI控制策略,可以有效提高输出电压和电流静态精度,使动态过程时间缩短、总谐波失真率减小,并通过仿真验证设计能较好提升UPS的供电质量。Compared with the battery, the online UPS is the direct power to the load through the inverter. The quality of the output power through the inverter is good or bad, which has great influence on the work of load. The paper presents the double closed loop PI control strategy which can effectively improve the accuracy of the static output voltage and current. The dynamic process is shortened and the total harmonic distortion is reduced. By the verification of the simulation, the quality of power supplied by the UPS can be effectively improved.
