Some configurations of universal active power filter (UAPF) with uninterruptible power supplies (UPSs) features for single-phase applications are proposed in this study focus on a reduced number of power electronic switches. All proposed configurations, composed by two-leg converters, compensate for current and voltage harmonics and provide power factor control close to one. Comparisons between the structures are made in terms of converters voltage capabilities, shared-leg, and capacitor currents. The model of the systems, including the equations and control system, is detailed described. Steady-state analysis of the proposed configurations demonstrates the existence of a load angle, which reduces the converters current, increasing the efficiency of the proposed systems. A complete set of simulated and experimental results are presented.

具有UPS功能的UAPF拓扑适用于中低压应用

本研究提出了针对单相应用的具有不间断电源(UPS)功能的通用有源电源滤波器(UAPF)的某些配置,重点是减少了功率电子开关的数量。所有建议的配置均由两脚转换器组成,可补偿电流和电压谐波,并提供接近于1的功率因数控制。根据转换器的电压功能,共享支路和电容器电流对结构进行比较。详细描述了系统模型,包括方程式和控制系统。对提出的配置进行的稳态分析表明存在负载角,这减小了转换器电流,提高了提出的系统的效率。提出了一套完整的模拟和实验结果。
