Abstract	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.
