METHOD AND CONTROL DEVICE FOR CHARGING OR DISCHARGING A PIEZO-ELECTRIC ACTUATOR

The invention relates to a method for charging or discharging a piezo-electric actuator (100), in particular of an injection valve of an internal combustion engine, wherein a first terminal (102) of the actuator (100) is set to a first reference potential (PB1) at least temporarily using a transfer...

Beschreibung
Zusammenfassung:	The invention relates to a method for charging or discharging a piezo-electric actuator (100), in particular of an injection valve of an internal combustion engine, wherein a first terminal (102) of the actuator (100) is set to a first reference potential (PB1) at least temporarily using a transfer inductance (L). The invention is characterized in that the actuator (100) is controlled dependent on a potential difference between the first reference potential (PB1) and a potential (P102) at the first terminal (102) of the actuator (100).
