摘要： The invention relates to power conversion and shaping of electric signals; it allows efficient generation of low voltage direct current power to high voltage and high current pulses suitable for driving piezoelectric manipulators and scanners. It overcomes problems associated with energy losses in traditional high voltage amplifiers and eliminates the need of feed-through connections for operation of piezoelectric devices inside pressure sealed volumes, such as controlled gas mixture, vacuum or temperature controlled chambers. The device comprises two stage voltage boost converters and full field-effect transistor bridge with pulse width limiter, which using the internal capacitance of the piezoelectric device, generates the required voltage waveform for inertial slider operation. The device also provides means to operate said piezoelectric devices in scanning mode.

摘要： The present invention relates to a dome-shaped piezoelectric linear motor, and provides a piezoelectric linear motor having enhanced displacement using dome-shaped piezoelectric ceramic. A dome-shaped piezoelectric linear motor (DSPLM) comprises: a dome-shaped piezoelectric ceramic actuator which has two surfaces applied with different electrodes; a bar-shaped vibration shaft which is vertically fixed at the apex of the dome-shaped piezoelectric ceramic actuator; a cylinder-shaped mobile element which is inserted into the vibration shaft and moves linearly along the vibration shaft; and a ceramic restraining element which is fixed at a lower edge portion of the dome-shaped piezoelectric ceramic actuator. Therefore, the vibration displacement in the direction of the vibration shaft is increased when compared to the vibration displacement in the thickness direction of planar piezoelectric ceramic.
