The objective of providing a circuit arrangement for the control of at
least one electric machine (1), which is suitable for also enabling
operating conditions of the electric machine (1) that demand high
power-peaks of short duration, is essentially achieved in that the
electric machine (1) can be connected via a DC/AC converter (2) and at
least one switching device (3) to at least two different electrical
energy storage devices (I, II), one storage device (I) being designed as
a storage device for comparatively long-lasting power demands and the
other storage device (II) as a storage device for short and high
power-peaks.
