Abstract:
A piezoelectric transformation driving apparatus for driving elements or products to be driven by a high or a low voltage, comprising:a pulse-width modulation (PWM) control unit for delivering output signals of a same phase and a same frequency; a plurality of driving units connecting to the PWM control unit and being driven synchronously by the signals of the same phase and the same frequency output by the PWM control unit; a plurality of transformation units connecting to the driving units and being driven by signals output by the driving units; a plurality of piezoelectric units connecting to the transformation units and being driven by signals output by the transformation units; and a plurality of loads connecting to the piezoelectric units and being driven by signals output by the piezoelectric units; wherein the signals of the same phase and frequency output by the PWM control unit synchronously drive the driving units, the transformation units, the piezoelectric units and the loads to operate.
