摘　　要：针对电网电压暂降和低电压问题,研究基于准比例谐振控制的单相动态电压恢复器。为保障在电压暂降后,输出电压能够快速准确地跟踪给定值,采用以输出电压为外环、以电感电流为内环的双闭环控制策略,并且外环调节器采用准比例谐振。搭建仿真模型和10k VA实验样机,对所提方法的正确性和有效性进行了验证。As to the voltage sag and low voltage of the grid, proportional resonant control based single phase dynamic voltage restorer was researched in this paper. Double closed-loop control strategy was adopted in or- der to the output voltage can track the reference rapidly and accurately, and in this scheme the output voltage was the outside loop and current in the inductor was treated as the inside loop. In the voltage loop, quasi proportional resonance was used for the controller. The simulation model and 10 kVA experimental prototype were built, and the proposed scheme was validated.
