CONSOLE ELECTRIQUE POUR OUTIL CHIRURGICAL COMPRENANT UN TRANSFORMATEUR AVEC UNE SOURCE DE COURANT INTEGREE POUR PRODUCTION D'UN COURANT APPARIE POUR COMPENSER LE COURANT PARASITE
Control console (50) for a powered surgical tool that includes a transformer (250) with a secondary winding (264) across which the tool drive signal is present. Also internal to the transformer is a matched current source that consists of a leakage control winding (246) and a capacitor (248). The current sourced by the matched current at least partially cancels out leakage current that may be present.
