Abstract
Model based predictive control is an interesting control method for power electronics as it offers many advantages. A known disadvantage compared to optimal pulse-width modulation control is the deteriorated voltage quality, which results in extra losses in the load. In this paper two ways of analyzing the output voltage quality are presented and applied on the model based predictive control of a three-level flying capacitor inverter. The influence of the weight factor and the system model are analyzed. The voltage quality is shown to be good in the same weight factor range as those resulting in good current and capacitor voltage control. No compromises have to be made in this area. A more accurate system model results in improved voltage (and overall control) quality.
