Abstract
(EN)
The purpose of the present disclosure is to provide a power conditioning circuit, a drive system, an actuator system, a moving body, and a power conditioning method, in each of which loss based on the generating efficiency of the actuator is unlikely to occur in the regenerative energy. A power conditioning circuit (1) is to be used with an actuator (2) which is driven by a driver (3) which receives a supply of power from a power storage device (4). The power conditioning circuit (1) is equipped with a regeneration circuit (11). The regeneration circuit (11) draws a regenerative current (I1) from the driver (3) and charges the power storage device (4) using the regenerative current (I1) when the output of the actuator (2) declines.

La présente invention vise à procurer un circuit de conditionnement de puissance, un système d'entraînement, un système d'actionneur, un corps mobile et un procédé de conditionnement de puissance, dans chacun desquels une perte basée sur l'efficacité de génération de l'actionneur est peu susceptible de se produire dans la puissance de récupération. Un circuit de conditionnement de puissance (1) doit être utilisé avec un actionneur (2) qui est commandé par un circuit d'attaque (3) qui reçoit une alimentation électrique à partir d'un dispositif de stockage électrique (4). Le circuit de conditionnement de puissance (1) comprend un circuit de récupération (11). Le circuit de récupération (11) extrait un courant de récupération (I1) à partir du circuit d'attaque (3) et charge le dispositif de stockage électrique (4) à l'aide du courant de récupération (I1) quand la sortie de l'actionneur (2) diminue.

本開示の目的は、回生エネルギに、アクチュエータの発電効率に応じた損失が発生しにくい、出力調整回路、駆動システム、アクチュエータシステム、移動体及び出力調整方法を提供することである。出力調整回路(1)は、蓄電装置(4)から電力供給を受けるドライバ(3)によって駆動されるアクチュエータ(2)用の出力調整回路である。出力調整回路(1)は、回生回路(11)を備える。回生回路(11)は、アクチュエータ(2)の出力を低下させる場合に、ドライバ(3)から回生電流(I1)を引き抜き、回生電流(I1)にて蓄電装置(4)を充電する。
