    Abstract: High power electro-acoustical transducer is one of the critical elements in sonar systems. The transducer’s properties strongly depend on the number of piezoelectric ceramic segments and mechanical elements such as head mass, tail mass, prestress rod and so on. In this research, a lumped equivalent circuit of electro-acoustic transducer is proposed. The relationship between the physical and electrical characteristics of the transducer is deduced. Then, the network theorem is implemented to design a high power transformer for impedance matching, and to improve the transmitting efficiency of the transducer.

    Since the transducer’s characteristic is evaluated by a automatic test system using Hp-Vee software program, the equivalent circuit of the electro-acoustic transducer with matching transformer was developed and simulated using Hp-Vee program. A practical design example is also presented in this research. The simulated results quite agree with the measured results. This approach actually develops an effective method for impedance matching design and reduced the time for trial and error.
