Abstract
A differential piezoelectric actuator-system includes an inductor and driver-circuit having switches for transferring energy between first and second actuators and the inductor, and between a voltage-supply node and the inductor. Control circuitry determines whether a next phase in which to operate the driver-circuit is a first charging-phase or a first recovery-phase. The first charging-phase includes operating the switches in: a first sub-phase to transfer energy from the first actuator to the inductor; a second sub-phase to transfer energy from the voltage supply node to the inductor; and a third sub-phase to transfer energy from the inductor to the second actuator. The first recovery-phase includes operating the switches in: a first sub-phase to transfer energy from the first actuator to the inductor; a second sub-phase to transfer energy from the inductor to the second actuator; and a third sub-phase to transfer energy from the inductor to the voltage supply node.
