ABSTRACT:
A device for driving at least one capacitive actuator contains a charge capacitor C1 and a discharge capacitor C2. According to the method, the actuator is charged with a desired voltage U.sub.s by the capacitors C1+C2 connected in series, and is then discharged into the discharge capacitor C2. The charge capacitor is then recharged to a voltage U.sub.C1 =U.sub.s -U.sub.C2 by a voltage source which can be regulated.
