The present invention relates to a direct current (DC)-based elevator power system. According to an embodiment of the present invention, the DC-based elevator power system comprises: a DC power conversion device converting alternating current (AC) power supplied from a system into DC power; a common DC power unit to which the DC power converted from the DC power conversion device is supplied; and one or more inverters receiving the DC power from the common DC power unit and converting the same into the AC power to supply the same to one or more winding machines for driving an elevator. According to the present invention, the power supplied to the winding machine of the elevator is supplied from the common DC power unit to reduce the number of conversions of AC and DC, thereby reducing power loss due to the conversion.

    본 발명은 직류 기반 엘리베이터 전원 시스템에 관한 것으로, 본 발명의 일 실시예에 따른 직류 기반 엘리베이터 전원 시스템은, 계통에서 공급되는 교류 전원을 직류 전원으로 변환하는 직류 전원 변환장치; 상기 직류 전원 변환장치에서 변환된 직류 전원이 공급되는 공통 직류 전원부; 및 상기 공통 직류 전원부에서 직류 전원을 공급받아 엘리베이터를 구동시키기 위한 하나 이상의 권상기에 공급하기 위해 교류 전원으로 변환하는 하나 이상의 인버터를 포함할 수 있다. 본 발명에 의하면, 엘리베이터의 권상에 공급되는 전원을 공통 직류 전원에서 공급되도록 하여, 교류 및 직류의 변환 횟수를 줄일 수 있어, 변환에 따른 전력이 손실되는 것을 줄일 수 있는 효과가 있다.
