Abstract

Based on power-flow-method

an effective approach for analyzing the electric property of PT(Piezoelectric Transformer)has been proposed in this paper.The main contributions are as the follows:(1).The formulas for calculating the optimal load

voltage's gain

efficiency

the output power of PT and so on have been derived;(2).According to these formulas

the procedure of finding out the electrical properties of PT has been put forward and the two new concepts

optimal load resistance and output matching network

have been introduced;(3).A few of simulated and exiperimental results have been given out to verify the conculsion.This approach is a very useful tool for analyzing the electric property of PT.
