Abstract

The invention is directed to a method and an arrangement (10) for controlling an electrically operated charger (1), which essentially prevent a sudden drop in voltage with the run-up of the electric charger. A drive signal (AS) is formed, which drives the electric charger (1). The rate of change of speed for an increase of the rpm of the electric charger (1) is pregiven in dependence upon the instantaneous supply voltage (UV).
