'''Asynchronous Drives''' | '''Asynchronous Drives''' can be fruitfully used for road vehicles, because it enable the cars to run in driving and in braking operations. Plug braking operations are also possible: this means that by using of the suggested feeding algorithm, ballast resistances may be eliminated, thereby and therefore the saving usable space. |
