Abstract:
1. A piezoelectric transformation driving apparatus, comprising: a control unit to receive a low voltage input and transmit a synchronous control signal; a ceramic transformer level driving unit receiving the control signal from the control unit and processing to output a first driving signal, the ceramic transformer level driving circuit including: a transformation unit connected to the ceramic transformer level driving unit and driven by the first driving signal input from the ceramic transformer level driving unit to transform to become a second driving signal to be outputted; a plurality of piezoelectric units connected to the transformation unit and driven by the second driving signal to transform through various polarization and polarity arrangements to become third driving signals of varying phases; and a plurality of loads connected to the piezoelectric units and driven by the third driving signals input from the piezoelectric units; wherein the transformation unit synchronously drives the piezoelectric units and the loads, and the ceramic transformer level driving circuit drives the transformation unit, the piezoelectric units and the loads to control a medium voltage system through a low voltage level.
