<p>The driver (10) for a piezoelectric slip-stick drive charges a capacitor (15) while applying a ramp voltage to a piezoelectric actuator (11) in such a manner that the charges on the capacitor (15) and the actuator (11) are equal but of opposite sign. At the end of the ramp, a switch (14) is used to connect the actuator (11) to the capacitor (15), which leads to a fast discharge.</p> |
