A charging circuit (102) for field devices (14) is disclosed. The circuit (102) has at least three modes and automatically shifts between the modes depending on voltage of the generator (100). In a first mode, the charging circuit (102) provides voltage regulation. In a second mode, the charging circuit (102) couples the generator (100) directly to an energy storage device (104). In a third mode, the charging circuit (102) decouples the generator (100) from the storage device (104). A field device (14) utilizing the charging circuit (102) is also disclosed.
L'invention concerne un circuit de charge (102) pour dispositif de terrain (14). Le circuit (102) possède au moins trois modes et passe automatiquement d'un mode à l'autre en fonction de la tension du générateur (100). Dans un premier mode, le circuit de charge (102) exerce une régulation de tension. Dans un deuxième mode, le circuit de charge (102) couple directement le générateur (100) à un dispositif de stockage d'énergie (104). Dans un troisième mode, le circuit de charge (102) découple le générateur (100) de son dispositif de stockage d'énergie (104). Un dispositif de terrain (14) utilise par ailleurs le circuit de charge (102).
