(WO9821805-A1)      The arrangement includes an electric machine operable as generator or as a starter, which is driven by a combustion engine, and which is connected over an intermediate circuit with a battery. The intermediate circuit includes at least one voltage converter and at least one converter.    The voltage converter is bridged by device of a switching element (20) at an operation of the machine as starter or as a generator underneath a pre-settable number of revolutions per minute, and the converter (14) is directly connected with the battery.    ADVANTAGE -   Reduces required power output at starting of engine.
