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.
