摘　　要：双口网络是电路理论教学中的一个重要的组成部分,如何让学生学好并灵活应用网络参数分析一些电路特性一直是电路理论教学探讨的问题。本文结合压电变压器的集总参数等效电路模型,在满足端口条件的前提下,分析压电变压器端口并—并、并—串、串—并和串—串的四种可能连接方式的特点,并利用参数之间的相互转换关系由Y参数描述压电变压器电压增益、输出功率和传输效率等电气特性。Two-port network is an important component of the teaching of circuit theory. How to allow students to learn and flexible application of the network parameters has been teaching circuit theory to explore the issue. Based on the conventional ]umped parameter circuit model, parallel-parallel, parallel-series, series-parallel and series- series connection are discussed. Then all the parameters are transformed to Y parameter in order to analyze voltage gain, output power and efficiency conveniently. Teaching results show these methods can help students to enhance their engineering concept, and arouse students＇ learning interest.
