초록

본 논문에서는 고성능 서버 및 무정전전원공급장치가 탑재된 함정용 통합 캐비닛에서의 무정전전원공급장치 운전모드별 잔류전류를 분석하였다. 무정전전원공급장치는 함전원 이상이나 순간 정전이 발생할 경우 전원을 공급해준다. 무정전전원공급장치는 임무 지속성을 확보하기 위해 구성이 필수이나 다수의 전력 변환단과 EMI 필터 및 바이패스 경로가 추가되므로 전원 연속성과 잔류전류 관리 사이의 설계적 절충이 필요하다. 제안 구조는 전원 연속성과 무정전전원공급장치의 기능을 유지하면서 통합 캐비닛의 잔류전류와 전원경로 간 상호영향을 줄이는 설계 대안으로 활용될 수 있다.

Abstract

In this paper, the residual current for each UPS operation mode was analyzed in a high-performance computer and an integrated cabinet for ships equipped with UPS. UPS is an essential configuration to ensure mission continuity, but a design compromise between power continuity and residual current management is required because multiple power conversion terminals and EMI filters and bypass paths are added. The proposed structure can be used as a design alternative to reduce the mutual impact between the residual current and path of the integrated cabinet while maintaining the function of power continuity and uninterruptible power supply.
