ABSTRACT:
A control device for piezo actuators of fuel injection valves includes a DC/DC up converter and an output stage configured as a SEPIC converter having a second transistor and a coupling capacitor connected in series on the input end. The DC/DC up converter is configured as a flyback converter having a transformer whose one connection of its secondary winding is connected to the connecting node of the second transistor and the coupling capacitor and whose other connection of its secondary winding is connected to the other connection of the coupling capacitor via a diode.
