ABSTRACT:
A piezoelectric power supply has a piezoelectric transformer circuit configuration which is alterable flexibly according to varying loading power requirements. It includes a control unit (control IC), a power switch (MOSFET) and an inductor to drive a piezoelectric transformer unit to actuate a high voltage and power load such as a cold cathode fluorescent lamp. The piezoelectric transformer unit consists of a plurality of piezoelectric transformers coupled in parallel. The specification of the piezoelectric transformers (single sheet piezoelectric transformers or low level laminated piezoelectric transformers) and parallel coupling number may be altered according to the required power of the load to change the voltage and current output by the piezoelectric transformers.
