Abstract
A device for charging and discharging a capacitive actuator connectable to an output connection has a first capacitor disposed between an input connection and a reference potential. The device has a series connection composed of a first and a second power switching element which is connected in parallel with the first capacitor. The device additionally has a first coil with a first connection connected to the center tap of the series connection, wherein the second connection of the first coil is connected to the reference potential via a third power switching element and to the output connection via a fourth power switching element. Wherein the power switching elements have diodes connected in parallel therewith such that they are reverse-biased from the input connection or the output connection to the reference potential. Wherein a connection of the fourth power switching element is connected to the input connection via a diode.
