Method for testing a capacitive actuator controls a capacitive actuator with a control signal of a certain duration related to predetermined or measured values for charging, discharging and opening durations.

摘要

A capacitive actuator is controlled with a control signal of a certain duration (T1), which is related to predetermined or measured values for charging, discharging and opening durations (T2-T4) according to the calculation (T1 + T3 - T2 - T4) <= X . Charging duration (T2) stretches from the beginning of a control signal (st) at a first time point (t1) up to a third time point (t3), in which an actuator voltage (Up) exceeds an upper voltage threshold (S3).
