Generalized Predictive Direct Power Control for AC/DC converters

Abstract

Predictive-Direct Power Control (P-DPC) is an attractive predictive control technique for AC/DC converters. This control strategy considers a dynamic power model of converter to forecast possible future converter behaviours. Thus, P-DPC provides an optimal switching pattern in order to directly control the active and reactive powers. Nevertheless, as will be shown in this work, this control method limits the converter operation range to a small power angle. In this work, we propose an improved P-DPC strategy, which allows one to extend the power angle operation range of an AC/DC converter while improving its power quality.
