APPLICATION OF A CONTROL VOLTAGE ACROSS A PIEZO ELECTRIC POSITIONING ELEMENT |
摘要 |
A device for the generation of a control voltage across a piezo-electric positioning element. In order to enable a high voltage to be generated across the piezo-electric element without using a comparatively high supply voltage, use is made of the capacitance of such an element as an integrating element. The device comprises a current source and switches for transferring current pulses to and from the piezo-electric element on command of control pulses. |
