Abstract:

© 2018 IEEE. This paper proposes a sequential Phase-Shifted Model Predictive Control (PS-MPC) strategy for three-level Active Neutral Point Clamped (3L-ANPC) converter. The proposed predictive control strategy is formulated to fully exploit a phase-shifted pulse width modulation (PS-PWM) stage. By means of an appropriate choice of synchronized average models for each carrier, the proposed predictive controller obtains independent optimal duty cycles for each carrier in a sequential manner. This allows one to formulate the optimal control problem not only to govern the output current but also to balance the dc-link capacitor voltages, similarly to the finite-control-set MPC (FCS-MPC) case. As evidenced by the simulation results, the 3L-ANPC converter governed by the proposed sequential PS-MPC can attain a faster dc-link voltage balancing dynamic when compared to a standard PS-PWM implementation. Moreover, it generates an output voltage with fix-spectrum in the steady state with a constant commutation rate and evenly distributed power losses, which outperforms a standard FCS-MPC strategy.
