  • Methods and devices for driving a piezoelectric pump
    Patent number: 11835037
    Abstract: A voltage driving apparatus for a portable fluid pump comprising a power source arranged to provide a direct current, a DC gain unit electrically connected, in use, to receive a voltage from the power source and output an amplified voltage, and a DC to AC conversion unit arranged, in use, to receive the amplified voltage from the DC gain unit and output a periodic waveform to drive a piezoelectric actuator in the portable fluid pump. The output periodic waveform comprises a first discrete voltage level and a second discrete voltage level. Each period of the waveform comprises the first voltage level for a first length of time and a second voltage level for a second length of time.
