Proposed is a circuitry and a related control mechanism for a vehicle with electric drive only or for a vehicle with hybrid drive comprised of an electric and a combustion motor. This circuitry has a multi-phase machine and two direct current units. Furthermore, an arrangement of power semiconductor components, in two converters in bridge arrangement of two semiconductor switches whose respective alternating current connections are connected in phase direction and to the connections of the multi-phase machine. The negative polarity connections of the two direct current units and the two converters are also connected to each other, the positive polarity connection of the first direct current unit is connected to the positive connection of the first convert by means of a flow control valve and the positive polarity connection of the second direct current unit is connected to the positive connection of the second converter by means of a flow control valve. Furthermore, a method is described for quasi-simultaneously supplying a multi-phase machine in motor operation from both direct current units and for supplying a first direct current unit from a second direct current unit with lower output voltage than the first one.
