摘要：

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. 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.
