Abstract
This paper proposes a control scheme based on predictive control for an Asymmetric Multilevel Converter, composed of a two-level inverter and two floating cells per phase. Main cell is handled by using a simple modulation that selects the sector of the reference vector and floating capacitor voltages are controlled to maintain an optimal asymmetry to maximize the number of load voltage levels with a small number of calculation, selecting only near sub-sectors and vectors of previous solution. This approach permits an improvement in the current quality and a reduction in the number of calculation. Results are presented in simulations.Keywords
