More Information
Summary:A method for regenerative driving of one or more transducers includes, for each of a plurality of driving cycles, enabling a number of transducers for driving, configuring a configurable capacitive energy storage element based on the number of enabled transducers and a desired overall capacitance, transferring a predetermined quantity of energy from a power supply to a first inductive energy transfer element, distributing the predetermined quantity of energy from the first inductive energy transfer element to the configurable capacitive energy storage element and to one or more other capacitive energy storage elements, each of the other capacitive energy storage elements coupled to an associated transducer, transferring energy from the one or more capacitive energy storage elements and from the configurable capacitive energy storage element to a second inductive energy transfer element, and transferring energy from the second inductive energy transfer element to the power supply.
