Abstract
A control system to suppress power Harmonic Components (HCs) when supplying an electric grid or motor characterized by un-ideal three-phase electro-motive forces (emfs) is presented in this paper. The proposed method can be applied in case of any three-phase emfs consisting of a certain number of HCs, each of which made up of positive-, negative-, and/or zero-sequence components. Based on emf features, different three-phase reference currents can be defined in accordance with the available degrees of freedom and power HC suppression targets. These reference currents are tracked by means of a deadbeat predictive current control algorithm, which is developed in the stationary reference frame to account for a possible wide and dense current harmonic spectrum. The effectiveness of the proposed solution is verified though a simulation study, whose results confirm the validity of the proposed theoretical approach.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
