The present invention provides a power conversion device for an electric bicycle, including: an alternator for generating an AC voltage; an inverter for converting the AC voltage generated by the alternator into a first DC voltage; a converter for reducing the first DC voltage to a second DC voltage having a lower level than the first DC voltage; a battery that is charged with the second DC voltage; and a control unit for controlling the converter to prevent the second DC voltage from exceeding the rated voltage of the battery.
본 발명은, 교류 전압을 생성하는 알터네이터와, 알터네이터에 의해 생성된 교류 전압을 제1 직류 전압으로 변환하는 인버터와, 제1 직류 전압을 이 보다 레벨이 낮은 제2 직류 전압으로 감압하는 컨버터와, 제2 직류 전압을 충전하는 배터리와, 제2 직류 전압이 배터리의 정격 전압을 초과하지 않도록 컨버터를 제어하는 제어부를 포함하는 전기 자전거의 전력 변환 장치를 제공한다.
