ABSTRACT:
A piezoelectric transformation driving apparatus to drive a plurality of high voltage systems through a low voltage system includes a control unit and a driving unit to output first driving signals of the same phase and same frequency to drive a transformation unit, a plurality of piezoelectric units and loads. A ceramic transformer level driving circuit may be included to drive the transformation unit, the piezoelectric units and loads through a voltage floating level so that a medium voltage system may be controlled by a low voltage level.
