Abstract

In this paper, we propose a model predictive control of current and voltage of a three-phase voltage-source AC/DC converter. A Li-Ion battery is connected to the AC/DC converter through a DC/DC converter. The AC/DC converter is composed of an inner-loop current controller and an outer-loop voltage controller. The voltage controller feedbacks the dc-link voltage and outputs a current reference to the current controller. The current controller outputs the optimum Pulse-Width-Modulation switching signals in the sense that it provides the nearest output current to the reference with the best convergence rate to the equilibrium point whose power factor is 1. A DC/DC converter regulates the current into (in constant current mode) or the voltage across (in constant voltage mode) the the battery.
