Space Vector Modulation (SVM) is a powerful method which enables some freedom to generate the modulation sequences and modify the performances of converter. However, in the multi-level converter structures, the number of switching state redundancies significantly increases, and the determination of modulation sequences becomes ambiguous because there are too many possible combinations and arrangements...
The three-level neutral-point (NP)-clamped (3L-NPC) converter is a promising multilevel topology in the application of megawatt wind power generation systems. However, the growing requirements by grid codes may impose high stress and even give reliability problem to this converter topology. This paper investigates the loss and thermal performances of a 10-MW 3L-NPC wind power inverter undergoing low-voltage...
When suing the multiple signal classification (MUSIC) direction finding algorithm based on uniform linear array, the estimation of the real arrival direction may be interfered due to the occurrence of the spurious spectral peak if the ratio of the element spacing to wavelength is more than 0.5. The available methods of eliminating spurious spectral peak are mainly suitable for active direction finding...
