Abstract
An electronic drive system for a droplet spray generation device has a droplet generator with a perforate membrane driven by a piezoelectric transducer. An electronic circuit controls a power supply to control the charging of a capacitor to supply a drive signal to the piezoelectric transducer. The electronic circuit is arranged to control the operation of the power amplifier at substantially its resonant frequency.
