analytical analysis, the dimensions of the transducer components were obtained such that the resonance frequency of transducer to be 22KHz for 3KW power emission. By using a 2D finite element model, a current source was connected directly to the model. Also, equivalent electrical-circuit models were developed. Then, the models were analyzed by ANSYS and resonance, anti-resonance frequencies and also voltage, current and equivalent impedance variations were obtained. Finally, simulation and experimental results were compared.
