Description: In this work, we propose a dual-stage control approach for a three-phase four-level Flying Capacitor Converter. The key idea of this proposal is to combine two control strategies to govern this converter. Thus, if the system state (output currents and floating voltages) is far from the desired reference, Finite-Control-Set Model Predictive Control is used to quickly lead the system towards the reference. Once the system state reaches a neighborhood of the reference, the propose control strategy switches to a PWM-based linear controller to finally achieve the desired reference in a gentle manner.
