The attractiveness of the smart piezoelectric technology is mainly due to its desirable features of miniaturization and the extreme simplicity of the resulting components compared to widely used wire wound conventional magnetics. As a result, much attention has been focused on the application of PETs in high frequency switching power supplies as well as low profile inverters. In this paper, performance study on Rosen-type, multilayer piezoelectric transformer (PET) as a potential component for power electronic conversion is presented. The equivalent circuit and impedance response of PET is studied using impedance analyzer HP4192. The effects of load resistance on voltage gain, output power and resonance characteristics are studied using simulations and experimentally under sinusoidal excitation conditions. A sinusoidal source using simple laboratory equipments and a power operational amplifier (POA) is fabricated. The details of this sinusoidal source are also given.

This paper discusses the characteristics of power-factor-correction (PFC) switching regulators of non-cascading structures in terms of efficiency, input current harmonic distortion, and load transient response. The discussion begins with simplified power flow diagrams of the non-cascading PFC switching regulators and describes their essential features for achieving power factor correction and tight voltage regulation. Based on these diagrams, the various configurations of switching regulators can be classified into three categories, each offering a different possibility of performance tradeoffs. The first category permits tradeoff between efficiency and input current harmonic contents, the second permits tradeoff between efficiency and load transient response, and the third allows tradeoffs among all performance areas. The paper briefly reviews the non-cascading structures of PFC switching regulators in terms of the three categories. Simulation and experimental results are provided to illustrate the performance tradeoffs in these PFC switching regulators.
