The bicentennial of the Voltaic battery (1800-2000): the artificial electric organ.
Alessandro Volta invented the electric battery at the end of 1799 and communicated his invention to the Royal Society of London in 1800. The studies that led him to develop this revolutionary device began in 1792, after Volta read the work of Luigi Galvani on the existence of an intrinsic electricity in living organisms. During these studies, Volta obtained a series of results of great physiolo...

متن کاملA Photo Voltaic System Based Dual Inverter
-This scheme presents an integrated solution for Photo Voltaic cell(PV) fed water-pump drive machine which uses an Open-End Winding Induction Motor (OEWIM). The dual inverter fed OEWIM drive achieves the functionality of a three level inverter and needs low value DC bus voltage. This helps in optimal arrangement of Photo voltaic cells, this can avoid large strings and helps in improving the PV ...
