Title (EN) LOAD DRIVE DEVICE
(FR) DISPOSITIF D'EXCITATION DE CHARGE
(JA) 負荷駆動装置
Abstract: front page image
(EN) This load drive device has: a first capacitor connected to first wiring; a second capacitor connected to second wiring; a first boost circuit, which is connected to a power supply that charges the first capacitor, and which generates, by boosting the voltage of the power supply, a voltage to be applied to the second wiring; and a connecting unit for passing a current from the second wiring to the first wiring in the cases where the voltage of the first wiring is reduced.
(FR) Ce dispositif d'excitation de charge comprend : un premier condensateur relié à un premier câblage; un second condensateur relié à un second câblage; un premier circuit survolteur qui est connecté à une alimentation électrique qui charge le premier condensateur, et qui génère, en amplifiant la tension de l'alimentation électrique, une tension à appliquer au second câblage; et une unité de raccordement pour faire passer un courant du second câblage au premier câblage dans les cas où la tension du premier câblage est réduite.
(JA) 第1の配線に接続される第1の容量と、第2の配線に接続される第2の容量と、第1の容量を充電する電源に接続され、電源の電圧を昇圧することで第2の配線に印加する電圧を生成する第1の昇圧回路と、第1の配線の電圧が低下した場合に、第2の配線から第1の配線への電流を通過させる接続部と、を有する。
