Control of a Multi-level Inverter with EMF prediction and single carrier-based space vector modulation

This paper presents a predictive control variant of a Multi-level Inverter that uses Space Vector Modulation with a single carrier. A linear model of the inverter is derived to predict the behavior of the EMF converter voltage and implement a current control law which uses the space vector modulation principle of the inverter. The fundamental of operation of this control strategy is described together with Saber numerical simulation results that validate the method with a 1kW prototype.
