Model predictive control of an active front end rectifier with unity displacement factor

Abstract

A finite control set model predictive control of an active front end (AFE) rectifier with unity displacement of input voltage and current has been investigated and presented in this paper. In this proposed control algorithm the discrete nature of the power converter are utilized and predicts the future behavior of the input system variables. Also the method selects the switching state that minimizes a cost function for firing the converter in the next sampling period. The proposed predictive control algorithm is validated through simulation and shows potential control and tracking of input unity power factor.
