Abstract

This paper proposes some topologies of universal active power filter for single-phase applications with reduced number of components. Some configurations are proposed: two with both series and parallel converters connected in half-bridge, sharing the same d.c.-bus mid-point connection; and the others with the series and parallel converters sharing one leg. It will be demonstrated the existence of a coupling law between the two converters (Se and Sh) related to the voltage capabilities. All configurations compensate current and voltage harmonic and provide power factor control close to unit. Comparisons between the structures are made and the steady-state analysis are also presented to demonstrate that it is possible to obtain an optimum voltage angle in order to reduced the amplitudes of the converters’ currents and, consequently, the total losses of the systems. Simulated and experimental results validate the theoretical considerations.
