Title: A NEW CONTROL SOLUTION USING FCS-MPC FOR A BIDIRECTIONAL INTERLEAVED CONVERTER OPERATING AS A DC POWER-FLOW INTERFACE

Keywords: Dc Power-Flow Interface, Interleaved converter, Model Predictive Control

Abstract
This work proposes a control solution based on finite control set model predictive control (FCS-MPC) for interleaved converters with the features of maintaining phase currents balanced and reducing the output current ripple while presenting a voltage regulation with a high disturbance rejection capability even under constant power loads. Moreover, the proposed solution adds a penalty strategy in the cost function to prevent overcurrent. Further, this work provides a secondary contribution, consisting of a method to estimate the predictive control bandwidth based on the disturbance rejection capability. The control analysis and the simulation results carried out throughout the work confirm that the proposed strategy solves the main issues of the interleaved converter and ensures the operation for applications in power flow interfacing between dc links.
