ABSTRACT:
A piezoelectric power supply includes a power supply unit to provide DC intermediate voltage power output to drive a high voltage output unit of a first load through a first piezoelectric plate and a low voltage output unit of a second load through a second piezoelectric plate. Thereby the power supply can provide a low voltage secondary power output to reduce cost and improve power output flexibility and efficiency. It can be used on display devices such as gas discharge lamps, and also provide additional low voltage secondary power for peripheral devices such as speakers, lamps, ear sets, USB connection ports and the like.
