The invention relates to a circuit for analogously controlling a capacitive charge (P), comprising a drive source (G) which is used to provide an operating voltage (Ul) or an operating flow which is used to charge the capacitive charge (P), a circuit arrangement (Q2, Q3) which is used to charge and discharge the charge (P), and a storage capacity (C) which is used to intermediately store the charge of the charge (P) during the discharge of the charge (P) and to emit intermediately stored charge to the charge (P) during charging of the charge (P). The invention also relates to a method for analogously controlling a capacitive charge (P) by applying a operational voltage (Ul) or an operating flow of a drive source (G) in order to charge the capacitive charge (P) onto the charge (P) and to discharge the charge (P). The invention is characterised in that during a first discharge phase, the charge of the charge (P) is intermediately stored in a storage capacity (C) and during a first charging phase, which is used to charge the charge (P), the charge from the charge capacity (C) is charged in the charge (P).
La présente invention concerne un circuit de commande analogique d'une charge capacitive (P) avec une source d'alimentation (G) conçue pour fournir une tension de fonctionnement (U1) ou un courant de fonctionnement afin de charger la charge capacitive (P), un ensemble de commutation (Q2, Q3) conçu pour charger et décharger la charge (P), ainsi qu'un condensateur de stockage (C) conçu pour stocker provisoirement le chargement de la charge (P) lors du processus de décharge de la charge (P) et pour délivrer le chargement stocké provisoirement à la charge (P) lors du processus de charge de la charge (P). Cette invention concerne de préférence également un procédé de commande analogique d'une charge capacitive (P), qui consiste à appliquer une tension de fonctionnement (U1) ou un courant de fonctionnement d'une source d'alimentation (G) afin de charger la charge capacitive (P) sur la charge (P) et de décharger la charge (P). Lors d'une première phase de décharge, le chargement de la charge (P) est stocké provisoirement dans un condensateur de stockage (C) et lors d'une première phase de charge pour charger la charge (P), le chargement provenant du condensateur de stockage (C) est chargé dans la charge (P).
