    In this paper, we studied the modeling of underwater loading conditions for piezoelectric transducers installed underwater for algae removal. Based on the finite element method, the impedance change according to the underwater environment was analyzed through multiphysics analysis of structure, piezoelectric effect, and ultrasound. In addition, the mechanical load modeling and impedance characteristics were analyzed and modeled according to each load condition of the Langevin type converter for inductance compensation used in the design of the existing electric driving circuit. Through this study, it is expected that it will be possible to design a power converter that enables efficient output control according to changes in the underwater environment.
