Proposal of a resonant controller for a three phase four wire grid-connected shunt hybrid filter

This paper present a three-phase four wire hybrid
\nfilter able to perform a selective cancellation of harmonic
\ncurrents based on resonant controllers. As it will be shown in
\nthis work, this kind of control permits to enhance the bandwidth
\nof the filter controller, without hindering the stability of the
\nsystem. In addition a new hybrid filter topology, that permits to
\ncancel out the homopolar harmonics, is presented in this paper.
\nThe good performance of this new topology as well as the
\nproposed controller will be evaluated by means of simulations
\nand experimental results.
