Compact, Efficient Drive Circuit for a Piezoelectric Pump

A switching circuit that drives a piezoelectric pump at a high voltage with a polarity that alternates at the desired mechanical pump frequency is described and depicted. This circuit offers advantages of (1) high energy efficiency relative to conventional direct-drive circuits and (2) compactness r...
