Abstract:
A drive system, in particular for a motor vehicle, comprising:a drive system in the form of a combustion engine (1);an electrical machine (4) that is or can be coupled with a drive shaft (10) of the drive system which rotates with the same number of revolutions as the drive shaft (10) and arranged in such a way that by running together, the drive system can be started from the idle state;at least one inverter (17) which produces the voltages and/or currents with variable frequency, amplitude and/or phase required for the magnetic fields of the electrical machine (4);wherein the inverter (17) has an intermediate circuit on a voltage level higher than that of the on-board electrical system, and in said on-board electrical system, a power storage device (11) is provided for storage of electric energy;and wherein on the higher voltage level of the intermediate circuit, another power storage device (19,24) is provided for storage of electric energy, and with an automatic start-stop control system within the scope of which the drive system is controlled by the electrical machine (4).
