Abstract :
A resonant driver for a piezoelectric motor (PZM) is presented, analyzed and tested experimentally. Following a short description of the linear PZM applied in this study, the paper covers the analytical relationships of the buck driven push-pull parallel resonant inverter stage that includes novel single transistor direction switches. It is shown that the proposed topology is compatible with the drive requirements of the PZM powered from a low voltage (24 V). It is also demonstrated that, unlike simple resonant converters, the proposed topology is relatively insensitive to the resonant component values and that it can tolerate added capacitance as introduced when connecting a PZM to the driver via a long cable
