Method of charging and discharging a piezoelectric element |
摘要 |
A method of charging or discharging a piezoelectric element, in which electric charge carriers are transported back and forth between a supply voltage of a direct voltage source and a piezoelectric element in order to transmit an elastic deflection of the piezoelectric element to an actuator. An actuating movement of the actuator is modified as a function of the level of a voltage being applied to the piezoelectric element, a reduction of the level of the applied voltage being compensated for by at least one additional transmission of electric charge carriers during a holding phase of the piezoelectric element.
