Piezoelectric transformers

Classically, the theoretical analysis of the electromechanical behavior of a piezoelectric transducer is based on the definition of a one-dimensional model that allows us to establish an equivalent electromechanical diagram in the form of a hexapole comprising one electrical and two mechanical ports (figure 5) [17][4]. This approach is based on a number of simplifying assumptions, such as the separation of coupling modes, linear operation and perfect interface conditions. It is therefore an idealized approach which, however, gives a good account of the transformer's...
