Abstract

As the import and export cargos across the world increase with global trade environments, the ecocide caused lots of small marine organisms in the ship's ballast water is a big issue. The implementation of the BWTS (Ballast water treatment system) thus needs low-voltage high-current rectifier for electrolytic disinfection. So this paper proposes a suitable high-current inverter-type rectifier for electrolytic disinfection of seawater and analyzes its output characteristics. It also suggests the practical design guidelines for the proposed rectifier in terms of power circuit and controller designs.

세계화와 더불어 수출 입 물동량이 크게 늘어남에 따라 세계를 왕래하는 선박의 평형수(Ballast water) 속에 존재하는 해양 유기체에 의한 생태계의 파괴가 큰 문제가 되고 있다. 이와 같은 문제를 해결하기 위해 국제규약은 선박의 평형수를 배출할 때는 반드시 미생물을 제거한 다음 바다로 배출할 것을 요구하고 있다. 이는 위한 염소발생용 전기분해 수 처리 시스템을 위해 우수한 성능을 가지는 저전압 대전류 방식의 정류기의 필요성이 커지고 있다. 본 논문에서는 선박의 평형수 처리를 위한 해수 전기분해용 정류기에 적합한 저전압 대전류 정류기 방식을 제안하고, 정류기 전력회로 설계와 제어기 설계에 필요한 실제적인 설계 가이드라인을 제시하고자 한다.
