Modelling and Analysis of Piezoelectric Transformers

Abstract

Piezoelectric transformers are well known since the end of the 1950s. One of the most prominent applications today is in the backlighting of LCD displays. Key features of piezoelectric transformers, such as light-weight, flatness, high step-up at low volume and high efficiency, make them attractive for a broad range of applications. The present paper first explains the operating principle of piezoelectric transformers and then concentrates on the modeling and analysis of such devices. Recent developments and potential future applications will also be discussed.
