Abstract:   (10316 Views)
The SVM is the well known technique for power converters with medium power and high voltage. However, the whole modulating procedure could be time-consuming for implementation purposes because of seeking the location of the reference vector in addition to performing so many necessary computations. Furthermore, computational cost for conventional SVM rises when level numbers of the multilevel converters increases. This paper proposes a modulation technique that directly concentrates on a three-phase system, engaging two independent line voltages in the procedure of finding switching states and their duty ratios. Interestingly, the proposed method is not only simple and fast, but also nearly eliminates the procedure of positioning the reference vector for multilevel converters that is vital for the conventional SVM. Through examples and simulations, the validity of the proposed method in modulation process is demonstrated.
