FCS – MPC and Feedback Quantizer applied to a Multi-Cell AFE Rectifier

In this paper is presented a proposal of control strategy based on Finite Control Set – Model Predictive complemented with Feedback Quantizer. Finite Control Set - Model Predictive is a control scheme widely used in power converters. The advantages of this control are, among others, (i) the nonlinearities and constraints of the converter’s operation, (ii) the natural discrete operation of power converters, and (iii) the rapid response to changes in references or disturbances. Yet, one drawback to be mentioned in the Finite Control Set – Model Predictive Control would be the non-fixed switching frequency, which results in a dispersed harmonic spectrum, generating resonance or saturation in transformers. The proposed control strategy, improve the harmonic spectrum of input current and PWM voltage of the power cell in a Multi-Cell AFE Rectifier. Simulation results confirm the validity of the proposal.
