Although a number of techniques exist for eliminating underwater microorganisms, the application of energy waves generated by high voltage is known to be effective in removing bacteria in marine ballast water. Generating such a high voltage requires particular electrical devices. These devices may be subject to different characteristics of high voltage generation, depending on their constituent elements. Given that the parameters of each element are regarded an important design factor, the resistance, inductance, and capacitance can be considered as key elements for stabilizing the output voltage in the circuit. This study developed electric circuits using the PSIM program to understand plasma phenomena in solution, by analyzing the respective characteristics of high voltage with different electric elements. We obtained meaningful results from the simulation, in consideration of the adverse effects of damping, overshooting, and undershooting on those elements. It was also found that excess power consumption might diminish the efficiency of the system performance. In addition, the water conditions, particularly the salinity % and the temperature rise owing to the arc discharge, were revealed to contribute to changing the degree of resistance. Therefore, the research outputs are believed to offer insights to key elements for producing high-voltage characteristics that can improve the effectiveness of eliminating bacteria from ship ballast water.
