Abstract
This invention drives a piezoelectric element by transferring energy from one element 5 to another 6 by way of an intermediate inductor 4. Additional energy is obtained from an energy source 1 to make up for internal losses and for the work performed by the piezoelectric elements. The energy is transferred as needed by switches which are operated by a controller for proper timing of energy transfer between the elements and energy boosts from the energy source.
