Abstract
This paper presents a solution for filtering current
harmonics in three-phase four-wire networks based on the usage
of a four-branch star (FBS) filter topology. The specific layout
of single-phase inductors and capacitors in this filter topology
allows achieving a power filter with two independent and
simultaneous resonance frequencies, i.e., one for positive-
/negative-sequence and another one for zero-sequence
components. The FBS filter topology can work either as a
passive filter, or as a hybrid filter, when its performance is
improved by integrating a power converter into its structure.
The paper analyzes the FBS topology and derives fundamental
concepts about the control of a generic FBS hybrid power filter.
From this analysis, a neutral current hybrid power filter and
var compensator is presented as an illustrative example
applying the FBS filtering topology to a three-phase four-wire
system. An evaluation using simulation and experimental results
is conducted as well.
