Abstract

Three-phase system has many problems because of the unbalance load. So we propose two control algorithms using active power filter to dissolve these problems. One is three-leg inverter topology in which ac neutral line is connected directly to the midpoint of two series dc capacitors. The other is four-leg inverter topology in which ac neutral line is provided through a fourth leg. The three-phase unbalance is considered by connecting the load to one-phase. It is show that the proposed control algorithms give good performances.
