The Characteristics of Cascaded Z-Source inverter and traditional Control strategy are analysed, and a maximum boost control strategy is proposed in this paper. Based on SPWM with third harmonic injection, all the zero vector states are replaced by shoot-through states, it can reduce the switching frequency as well as improve the shoot through duty cycle(More)
The unsupervised method of growing hierarchical self-organizing map (GHSOM) was used to perform mental tasks classification. The GHSOM is an adaptive artificial neural network model with hierarchical architecture that is able to detect the hierarchical structure of data. The results indicate that GHSOM provides more detailed clustering information than SOM,(More)
