This paper presents a new solution for filtering current harmonics in three-phase thee-wire medium
voltage networks. The hybrid filter topology presented in this paper is characterized by the use of an HBridge
instead of the usual thee-phase inverter. This H-bridge is directly connected in series with a passive
filter tuned around sixth harmonic. This paper provides a theoretical explanation on voltage control of Hbridge
in three-phase systems. The good performance of this new topology as well as the proposed
controller will be evaluated by means of simulations.
