摘要

压电变压器是一种非常有前途的固态电子器件

同传统的电磁变压器相比具有器件结构简单、体积小、效率高、无电磁噪声、无电磁式绕组及不可燃烧

安全性高等特点

而且在大规模生产下的成本可以大幅降低.本文采用等效电路模型对该器件的升压比(增益) 、输出功率、功率传输效率进行了理论分析和计算

并用实验手段对其加以验证.利用压电变压器制作的CCFL驱动器和DC-DC变换器的电路也在文中给出.

Abstract

Piezoelectric transformer is a kind of very promising solid electronic component which has the following several merits compared with the traditional magnetic transformers:it has very simple structure

small volume

high efficiency

no magnetic noise

no windings so uninflammable

high safety

and low cost under mass production.In this paper

the properties of piezoelectric transformer such as the step-up ratio of voltage

output power

efficiency

etc.are analyzed and calculated through equivalent circuit model.The accuracy of the model is verified by experiment.Two applications circuits:CCFL driver and DC-DC converter using piezoelectric transformer are given.
