Summary:A method and a system for providing power to an elevator hoist motor are disclosed. An isolated bi-directional DC/DC converter is coupled between a power converter and a power inverter. A battery is coupled to the isolated bi-directional DC/DC converter. A processor is configured to sense power levels and couple the battery to an elevator hoist motor via the isolated bi-directional DC/DC converter depending on voltage of main power supply. The isolated bi-directional DC/DC converter is also configured to provide power to charge the battery. 엘리베이터 호이스트 모터에 전력을 제공하기 위한 방법 및 시스템이 개시된다. 고립된 양방향 dc/dc 컨버터가 전력 컨버터와 전력 인버터 사이에 연결된다. 배터리가 고립된 양방향 dc/dc 컨버터에 연결된다. 프로세서가 전력 레벨을 감지하고 메인 파워 서플라이의 전압에 따라 고립된 양방향 dc/dc 컨버터를 통해 배터리를 엘리베이터 호이스트 모터로 연결하도록 구성된다. 고립된 양방향 dc/dc 컨버터가 전력을 제공하여 배터리를 충전하도록 구성된다.
