The present invention relates to an exterior power supply cathodic protection system for a ship. More specifically, the present invention relates to the exterior power supply cathodic protection system for the ship which uses a DC/DC converter to output a stable protection current with a small ripple through an anode. According to the present invention, an AC/DC converter and the DC/DC converter are used to supply a stable voltage and the current through PWM control. Therefore, stable protection of a hull can be achieved. Additionally, a battery, an electricity source, and a solar system are utilized. Therefore, the protection current is supplied even in an emergency situation such as a failure of the AC/DC converter or blackout of the ship. Therefore, protection of the hull can be achieved in any situation. The exterior power supply cathodic protection system for the ship of the present invention comprises: the AC/DC converter; the DC/DC converter; a first voltage sensor; and a control unit.
본 발명은 선박용 외부전원 음극방식 시스템에 관한 것으로, 더욱 상세하게는 DC/DC 컨버터를 활용하여 양극을 통해 리플이 작은 안정된 방식전류를 출력하는 선박용 외부전원 음극방식 시스템에 관한 것으로, AC/DC 컨버터 및 DC/DC 컨버터를 활용함으로써 PWM 제어를 통한 안정된 전압과 방식전류를 공급하여 선체의 안정적인 방식이 가능하며, 배터리, 전력원과 태양광 시스템을 활용함으로써, AC/DC 컨버터의 고장이나 선박의 블랙아웃과 같은 비상 상황 발생 시에도 방식전류를 공급하여 어떠한 상황에서도 선체의 방식이 가능하다는 효과가 있다.
