This paper presents important characteristics on the study of universal filters topologies. The
integration of series and shunt active power filter was
proposed by [1], where the two converter shared the
same dc-link bus voltage. By a steady state analysis it
was noted that there is a higher difference between two
voltage converters. The voltage capability of shunt convert
is more than series converter for the most situations.
This way, the authors proposed a topology with two
dc-link voltages, to better design the converters voltages
capabilities , consequently reduce the THD and power loss.
By the steady state analysis it possible to show the limits
of operation and the better parameters for: transformer
turn ration and passive filters.
