Abstract:
(EN) An energy collecting device capable of reusing residual charges by using a piezoelectric element, presented in the present invention, comprises a piezoelectric element, a rectifier, a charge/discharge changing unit and a digital controller, wherein a plurality of capacitors provided in the charge/discharge changing unit are changed to a series or parallel connection under a charge mode or a discharge mode, such that a connection state of the plurality of capacitors can be sequentially changed to whole parallel, partial series and whole series through the control of a digital signal in correspondence to a driving voltage for driving a load in the discharge mode, thereby enabling residual charges in the respective capacitors to be reused as much as possible in correspondence to the driving voltage for the load.
(FR) La présente invention concerne un dispositif de collecte d'énergie pouvant réutiliser des charges résiduelles à l'aide d'un élément piézoélectrique, comprenant un élément piézoélectrique, un redresseur, une unité de changement de charge/décharge et un contrôleur numérique, une pluralité de condensateurs disposés dans l'unité de changement de charge/décharge étant changés en un montage en série ou parallèle dans un mode de charge ou un mode de décharge, de telle sorte qu'un état de montage de la pluralité de condensateurs peut être changé séquentiellement en montage entièrement parallèle, partiellement en série ou entièrement en série par le biais de la commande d'un signal numérique en correspondance avec une tension de commande pour entraîner une charge dans le mode de décharge, ce qui permet de réutiliser autant que possible les charges résiduelles dans les condensateurs respectifs en fonction de la tension de commande pour la charge.
(KO) 본 발명에서 제안하고 있는 압전소자를 이용한 잔존 전하의 재사용이 가능한 에너지 수집 장치에 따르면, 압전소자와 정류기와 충/방전 변환부 및 디지털 컨트롤러를 포함하는 에너지 수집 장치에서, 충/방전 변환부에 구비되는 복수의 커패시터가 충전 모드 또는 방전 모드 하에서 직렬 또는 병렬로 변환하되, 방전 모드 하에서 부하가 구동하기 위한 구동 전압에 대응하여 디지털 신호의 제어를 통해 복수의 커패시터의 접속 상태가 전체 병렬, 부분 직렬, 및 전체 직렬로 순차적으로 변환 연결될 수 있도록 함으로써, 부하의 구동 전압에 대응하여 각각의 커패시터에 잔존하는 전하를 최대한 재사용할 수 있도록 할 수 있다.
