Abstract—Nowadays, most of the driving powers of PZT
( lead zirconate titanate ) pumps are large, less efficient, and
high power consumption. This paper presents a new type of a
driving power supply composed of the step-up inverter for a
PZT liquid pump. In order to provide a square wave of ±40V
and 50 Hz for a PZT liquid pump, this design used the MC34063
and NE555 integrated circuits to respectively fabricate a
DC-DC boost circuit as well as a full-bridge inverter circuit.
The performance of the driving power supply is verified by the
theoretical statement and practical test. Besides, the liquid
pump is composed of a PZT, elastomer pump valve, and PET
( Polyethylene terephthalate ) pump body, while the power, flow
rate, body size and weight of the pump are 1 W, 800 ± 5% ml
min-1, 50 × 50 × 10 mm., 50 gw, respectively. Furthermore, the
PZT liquid pump is suitable for various fluids such as water,
soda, alcohol, etc.
Index Terms—Piezoelectric, boost converter, PZT,
