Abstract
In this paper control systems suitable for a 4-leg NPC converter are discussed. The proposed control methodology is based on a finite set model predictive control. A theoretical analysis of the strategy, including tracking of non-sinusoidal currents and reduction of the switching frequency, is presented in this paper and experimental results, obtained with a 3 kw experimental prototype are discussed.
