Abstract
To minimize the energy required for operation of a rail vehicle, in a drive system that has an intermediate circuit converter and a three-phase motor fed by it, the intermediate circuit voltage in the intermediate circuit and/or the magnetic flux in the drive motor are optimized to correspond to the actual operating requirements, including, if necessary, the energy expenditure for the auxiliaries that are provided to cool the components.
