In recent years, Model Predictive Control (MPC) has been successfully applied to the control of power electronics converters with different topologies and for different applications. MPC offers many advantages over more traditional control techniques such as the ability to avoid cascaded control loops, easy inclusion of constraint and fast transient response. Finite Control Set Model Predictive Control considers the discrete nature of power electronics converters to simplify the control derivation and implementation. In order to show the capabilities of Finite Control Set Model Predictive Control, this paper proposes an application of such technique to parallel three-phase boost rectifiers control, where AC active and reactive power, DC voltage and zero Sequence power are controlled within one single control loop. The proposed control approach is validated through simulation, and results are provided in several operating conditions.
