Abstract
A control arrangement for operating a locking system having an electric drive. During normal operation the electric drive is fed by a normal supply voltage in order to provide a motorized locking function for an adjustable closing element. The control arrangement has an energy storage arrangement having at least one energy store in the form of a capacitor. In an emergency operating mode the energy storage arrangement makes available an energy storage voltage. A main boost stage is connected downstream of the energy store. The energy storage voltage is applied to an input of the main boost stage in the emergency operating mode and the main boost stage boosts the energy storage voltage to the emergency supply voltage. An auxiliary boost stage to also be connected downstream of the energy store and to be able to be connected upstream of the main boost stage.
