Abstract

Robust sliding mode on-line space vector controllers, designed for output current control in multilevel three-phase power inverters are described. Capacitor voltage divider equalisation is included using the same approach. Using two four-level comparators, simulation and experimental results show no steady state-errors, very fast dynamics and robustness against power supply variations and load unbalances
