TL;DR: This paper presents a complete comparative study about the five most common configurations of shunt active power filter applied to four-wire distribution systems and shows that structures with fourth inductor generate higher number of levels at output converter voltage when they operate by compensating high levels of zero-sequence harmonics.

TL;DR: In this article, a single-phase to three-phase drive system composed of two parallel singlephase rectifiers, a threephase inverter, and an induction motor is proposed to reduce rectifier switch currents, the harmonic distortion at the input converter side, and presents improvements on the fault tolerance characteristics.

TL;DR: In this paper, a shunt active power filter based on the concept of open-end winding (OEW) transformer for three-phase three-wire systems is presented, which is suitable for medium-voltage distribution systems.

TL;DR: In this article, a shunt power compensator based on the interconnection of three-phase two-level converters, and its comparison with two level and multilevel-based topologies are presented.

TL;DR: In this paper, the authors investigated power shunt filter topologies composed of three standard three-leg converters applied in either three or four-wire system and compared them with the usual three-phase shunt filters.
