|1. (WO2018204897) ACOUSTIC TRANSDUCER CONTROLLER CONFIGURATION|
|Applicants:||FLODESIGN SONICS, INC.
|Title:||ACOUSTIC TRANSDUCER CONTROLLER CONFIGURATION|
An RF driver provides power to an acoustic transducer, which can be implemented as a piezoelectric element, which presents a reactive load. The driver can be a linear amplifier or a combination of a DC-DC converter and DC-AC inverter. A controller implements a control technique for efficient transducer operation. The control technique can locate a frequency for operation that is at a reactance minimum or maximum for the transducer to provide efficient operation of that transducer. An implementation of the controller can be provided in modular hardware.
