The invention concerns a drive system, especially for a motor vehicle, with a multicylinder internal combustion engine, a device for shutting off at least some of the cylinders of the internal combustion engine, and a device for active reduction of rotational nonuniformities, acting in particular on a shaft, such as a drive shaft of the internal combustion engine, or a shaft that is coupled or which can be coupled to it, which is active at least for certain operating states during cylinder shutoff mode. A method of operating such a drive system is also disclosed.

1. Drive system, particularly for a motorized vehicle, comprising:a multi-cylinder combustion engine; a device (31 or 33) to switch off at least one cylinder of the combustion engine (1); an electric rotating field motor (4) to provide active damping of rotational non-uniformities by creation of varying torques, whereby the electric motor (4) is active for damping of the greater rotational non-uniformity during operation with cylinder(s) switched off; at least one alternating current rectifier (17 used to create the voltages and/or currents of variable frequency, amplitude and phase required for the magnetic fields of the electric motor (4)' whereby the alternating current rectifier (17) features an intermediary circuit is equipped with an energy buffer (19, 24) for intermediary storage of energy arising during active damping; whereby both the energy production from the intermediary circuit during engine operation of the electric motor and the energy storage into the intermediary circuit during generator operation occur at the higher voltage level.
