Abstract
A multi-layer piezoelectric transformer (PT) is provided that is capable of achieving high mechanical momentum and, therefore, is capable of high energy transmission. The PT has a plurality of layers arranged as a composite structure. The outermost portions of the PT comprise the input portions, which are bonded to the central output portion of the PT. The construction and anisotropic nature of the PT allows it to be driven at the longitudinal resonant frequency of the PT corresponding to its overall thickness, which increases the achievable gain and power density of the PT.
