(FR) MACHINE À SOUDER ALIMENTÉE PAR BATTERIE UTILISANT UN ONDULEUR DE VÉHICULE
Abstract
(EN)
A system and method, in certain embodiments, adjusts a charging output based on capabilities of various power sources. The system and method may be used to charge a variety of equipment such as welders, cutters, induction heaters, tools and so forth. For example, a charging circuit configured to change an output charge level based upon capabilities of multiple power sources configured to be coupled to the charging circuit. In some embodiments, the system and method may test the capabilities of the various power sources by evaluating an actual output versus a commanded output, and reduce the commanded output if the actual output falls below a desired level.
(FR)
La présente invention concerne, dans certains modes de réalisation, un dispositif et un procédé permettant de régler une sortie de charge selon les capacités de diverses sources d'alimentation. Le dispositif et le procédé peuvent servir à charger une variété de matériel, tel que des machines à souder, des fraises, des appareils chauffants à induction, des outils, etc. Par exemple, un circuit de charge est conçu pour modifier un niveau de charge de sortie selon les capacités de plusieurs sources d'alimentation conçues pour un couplage au circuit. Dans certains modes de réalisation, le dispositif et le procédé peuvent tester les capacités des diverses sources d'alimentation par évaluation d'une sortie réelle par rapport à une sortie commandée, et réduire cette dernière si la sortie réelle est inférieure à un niveau souhaité.
