TL;DR: The results show that the predictive method controls very effectively the load current and performs very well compared with the classical solutions.

TL;DR: This new control method is an attractive alternative to the classic multilevel pulsewidth modulation techniques considering the following aspects: voltage and current total harmonic distortion; range of linear operation; and number of commutations.

TL;DR: In this paper, a control method for cascaded H-bridge multilevel converters for grid connection of photovoltaic systems is analyzed, which is based on traditional voltage oriented control with a cascaded dc-link voltage control and grid current control loop, two extra stages are added to this traditional control scheme, one to introduce maximum power point tracking for each module or string, and another to control the dclink voltages drift due to circulating power in the converter.

TL;DR: In this paper, a switching strategy for multilevel cascade inverters, based on the space vector theory, is presented. But the proposed switching strategy generates a voltage vector with very low harmonic distortion and reduced switching frequency.

TL;DR: This paper presents a switching strategy for multilevel cascade inverters, based on the space-vector theory, which generates very low harmonic distortion operating with reduced switching frequency, without the use of traditional sinusoidal pulsewidth modulation techniques or more sophisticated vector modulation methods.
