Abstract:
Control console for a powered surgical tool (310) 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 leakage control winding (246) and a capacitor. The current sourced by the matched current source at least partially cancels out leakage current that may be present.
