Non-Equilibrium State Capacitor Voltage Stabilization in a Hybrid Asymmetric Nine-Level Inverter: Non-Linear Model-Predictive Control

Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage industrial drives. Floating sub inverters without feeding allow increased efficiency, but can only supply reactive power. An on-line non-linear model-predictive controller stabilizes their intermediate-circuit capacitor voltages in steady-state and during transients, as demonstrated by simulations and measurements.
