Modulated predictive current control technique for a three-phase four-wire active power filter based on H-bridge two-level converter

Abstract

Finite-control-set model-based predictive current control (FCS-MPCC) technique is distinguished by a variable switching frequency which causes high harmonic distortion a low sampling frequency. This latter could be considered an undesired behavior for active power filter for grid-connected applications. To overcome this issue, this paper proposes a modulated FCS-MPCC applied to a three-phase four-wire active power filter based on H-bridge converter. Simulation results are developed to demonstrate the efficiency of the proposed modulated FCS-MPCC comparing with classic FCS-MPCC, thus concluding the advantages and limitations of each technique at transient and steady states.
