Device for controlling a regulator

摘要

An actuator comprises a gas exchange valve and an electromagnetic actuating drive, having at least one electromagnet which has a coil, having an armature, whose armature plate can move between a first bearing surface on the electromagnet and a second bearing surface. A device for controlling the actuator comprises a power output stage provided for driving the coil. The power output stage has an electrical energy store which is charged by the coil in a predetermined operating state. The control unit controls the power output stage in an operating state of rapid energization when a predetermined condition is met indicating the striking of the armature plate on the first bearing surface or an imminent fallback of the armature plate to a rest position, the energy stored in the electrical energy store being fed to the coil in the operating state of rapid energization.
