Current control based on space vector modulation applied to three-phase H-Bridge STATCOM

This paper presents a modulated model predictive current control (MPC) based on space vector analysis applied to a three-phase H-Bridge STATCOM. This article proposes a modulation strategy, based on space vector modulation in α- β subspace, in order to mitigate the propagation of the THD of the current injected in the point of common coupling (PCC). Simulation results based are provided to quantify the performance, in terms of power RMS ripple and mean square error (MSE) of the measured phase currents and their corresponding references, of the proposed modulated predictive current control.
