|
摘要
根据压电晶片厚度振动一维等效电路、传输线理论和超声传播理论提出一种PSPICE等效电路模型.该模型利用有损传输线可对压电晶片的机械损耗过程进行模拟仿真.利用该模型对超声无线输能系统声电转换通道进行了PSPICE等效电路建模和仿真,不仅得到了快速可靠的计算结果,而且简化了超声无线输能系统的电路设计过程.该方法为研究超声无线输能系统提供了有效可靠的理论和技术基础.
According to the one-dimensional equivalent circuit of piezoelectric thickness-mode transducer,transmission line theory and ultrasonic propagation theory,a PSPICE equivalent circuit model was proposed. The model can model and simulate the mechanical loss process of piezoelectric transducer by using lossy transmission line. By using this method,the PSPICE equivalent circuit modeling and simulation of the electro-acoustic conversion channel of the ultrasonic wireless transmission system was carried out. The fast and reliable calculation results were obtained,and the circuit design process of the ultrasonic wireless energy transmission system was simplified. This method provides an effective and reliable theoretical and technical basis for the study of ultrasonic wireless transmission system.
