The present invention relates to an emergency rescue device for an elevator having a power regeneration function and an elevator drive system including the same. The present invention includes: an elevator inverter including a converter converting AC power applied through a reactor into DC power with the reactor and a breaker connected in series to a commercial power supply, a capacitor smoothing the DC power of the converter, and an inverter converting the DC power smoothened through the capacitor into AC power for supply to an elevator motor; an emergency rescue device boosting battery charging power and then converting the power into a three-phase AC voltage for supply to the elevator inverter in an emergency operation mode such as a power failure and, in a normal operation mode, receiving regenerated power generated by an elevator motor during elevator operation from the elevator inverter, converting the power into a three-phase AC voltage for supply to the elevator inverter in synchronization with the frequency and phase of the commercial power supply; and a control unit performing selective supply control of the battery charging or regenerated power in accordance with the operation mode.

    본 발명은 전력 회생 기능이 부가된 엘리베이터의 비상구출장치(ARD) 및 그를 포함하는 엘리베이터 구동 시스템에 관한 것으로, 상용전원에 차단기와 리액터가 직렬 접속되고, 상기 리액터를 통해 인가되는 교류 전원을 직류로 변환하는 컨버터와 상기 컨버터의 직류전원을 평활하는 콘덴서 및 그 콘덴서를 통해 평활된 직류전원을 교류 전원으로 변환하여 엘리베이터 모터로 공급하는 인버터를 구비하는 엘리베이터 인버터와; 정전과 같은 비상운전모드에서는 배터리 충전 전원을 승압후 3상 교류전압으로 변환하여 상기 엘리베이터 인버터에 공급하고, 정상운전모드에서는 엘리베이터 운전시 상기 엘리베이터 모터에 의해 발생되는 회생전력을 상기 엘리베이터 인버터로부터 전달받아 3상 교류전압으로 변환하여 상기 엘리베이터 인버터로 공급하되 상용전원의 주파수와 위상에 동기화시켜 공급하는 비상구출장치와; 운전모드에 따라 상기 배터리 충전 전원 혹은 상기 회생전력을 선별 공급 제어하는 제어부;를 포함함을 특징으로 한다.
