Lead-free multilayer piezoelectric transformer.

In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94(Bi(12)Na(12))TiO(3)-0.06BaTiO(3) ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3 mm long, 8.3 mm wide, and 2.3 mm thick. It operates in the second thickness extensional vibration mode. For a temperature rise of 20 degrees C, the tran...

Laptop Adaptor Using a Piezoelectric Transformer -Drive Circuit Development-

This paper describes incorporation of a piezoelectric transformer into a laptop computer adaptor in order to miniaturize the size and improve the energy utilization. Conventionally, electromagnetic transformer is used in the adaptor for generating the 45W output power. In this study, we show that a multilayer piezoelectric transformer rated 30W output power can satisfy the laptop specifications...

Solver for a Magnetic Equivalent Circuit and Modeling the Inrush Current of a 3-Phase Transformer

Knowledge about the magnetic quantities in a magnetic circuit is always of great interest. On the one hand, this information is needed for the simulation of a transformer. On the other hand, parameter studies are more reliable, if the magnetic quantities are derived from a well established model. One possibility to model the 3-phase transformer is by using a magnetic equivalent circuit (MEC). T...

Numerical And Analytical Modeling Of The Piezoelectric Transformer And Experimental Verification

In this paper, to approach the modeling aspect, we have selected a Rosen-type structure of piezo-electric transformer which, for us, seems very interesting from an educational point of view. Two approaches will be presented ; (i) The first one consist of performing the analysis with an electric equivalent circuit. The set of hypotheses used in the equivalent circuit method prove to be somewhat ...

Modeling and Simulation of Multiple Piezoelectric Transformer Converters

Piezoelectric transformers (PT) are an alternative to wire wound magnetic transformers because of numerous advantages i.e. being the electromechanical energy conversion, low EMI, a compact and low design, as well as a high potential of high efficiency and power density. The last two decades of research into piezoelectric transformer (PT) based power converters have led to some extensive improve...
