摘　　要：文中提出了一种基于积分复位控制的新型单相UPS系统。文章通过推导其小信号模型，给出了控制器具体的设计方法。仿真结果证明了该控制策略最显著的优点是：对输入电压的大扰动具有很好的抑制性，负载变化时具有较好的鲁棒性，而且在带非线性负载时输出电压波形的质量很高。This paper proposes a novel single - phase UPS system based on reset integral control. The design scheme for control is presented through deduction of small signal model. Simulation results prove that the most prominent advantages of this control scheme are high rejection to large disturbances of input voltage, satisfied robustness with variable loads and high quality of the wave shape of output voltage with nonlinear loads.
