An ultrasonic anti-fouling system that works to remove bio-fouling, which is organic substances attached to structures under the water surface of a ship, while the ship is anchored is proposed. In order to review the configuration and applicability of the proposed system, it is designed by analyzing the operation patterns of coastal small ships and simulating power consumption according to the operation patterns. In this paper, a 500W class converter is proposed among the proposed system. To achieve high performance, a continuous conduction mode that can reduce the size of a circuit and improve efficiency of the system is applied, a two-phase interleaved boost converter applied to schottky diode and N-MOSFET power switch which are capable of high-speed switching is designed. In addition, P&O method that is easy to implement and has a simple structure among MPPT control algorithms is applied to track the optimal operating point in the non-liner characteristics of independent power module. To verify the usefulness of the proposed system, a 500W class power converter is designed. Through simulations and experiments, the performance of the MPPT algorithm according to the solar radiation condition of the independent power module and the two-phase interleaving algorithm are verified. In particular, the MPPT efficiency of over 99.6% is confirmed even under environmental conditions where the amount of solar radiation rapidly changed from 100% to 75% and the power conversion efficiency at 500W output is confirmed to be 96.26%, confirming the usefulness of the proposed circuit.
