Modulação rápida para inversores multiníveis sem transformação de coordenadas.

Abstract

This works presents a space vector modulation strategy and it's application aiming three di erent objectives: reduction of the harmonic distortion, common-mode voltage elimination and operation under faulty conditions. The method is based on the flexibility to select the switching states proportioned by the space vector technique. Then, was developed three di erent algorithms for vector selection according to the strategy's objective. The solutions presented can be used in inverters of any number and are most suited for FPGA implementation. The strategies were compared with other techniques from literature and the results demonstrate the efficiency and quality of the proposed solutions.
