Abstract

무정전 전원 공급 시스템은 동작 모드가 정상 모드인 경우 단상 교류 입력 전압을 부하 및 배터리로 제공하고, 동작 모드가 정전 모드인 경우 배터리의 전력을 단상 교류 출력 전압으로 변환하여 부하로 제공하는 복수의 무정전 전원 장치들을 포함한다. 구성 모드가 단상 병렬 모드인 경우 복수의 무정전 전원 장치들 각각은 단상 교류 입력 전압을 공통으로 입력받아, 단상 교류 출력 전압을 공통으로 출력한다. 구성 모드가 3상 모드인 경우 복수의 무정전 전원 공급 장치들은 적어도 세 개의 무정전 공급 장치들을 포함하고, 상기 적어도 세 개의 무정전 공급 장치들 각각은 3상 교류 입력 전압의 서로 다른 상 전압을 독립적으로 입력받아 3상 교류 출력 전압의 서로 다른 상 전압을 출력한다.
