Abstract: A control console (50) for a powered surgical tool (330). The console includes a transformer (250) that supplies the drive signal to the surgical tool. A linear amplifier (115) with active resistors (162, 184), selectively ties the ends of the transformer primary winding between ground and the open circuit state. Feedback voltages from the transformer windings regulate the resistances of the active resistors.

Abstract: A control console (50) for supplying an AC drive signal to the power generating unit (344) of a powered surgical tool (330) is disclosed, wherein the console (50) includes a transformer (250) with: a primary winding (252) with opposed ends and a center tap to which a DC voltage is applied; and a secondary winding (258) across which the AC drive signal is induced for application to the tool power generating unit (344). The console (5) also includes transistors (162, 184) tied to the ends of the transformer primary winding (252) and ground that are selectively turned on/off to cause an AC voltage to develop across the primary winding (252), wherein the transistors (162, 184) are operated as active resistors. Also included is a variable DC power supply assembly regulating the level of the DC voltage applied to the center tap of the transformer primary winding (252). Further provided is a headroom monitor (190) connected to the ends of the transistors (162, 184) connected to the ends of the transformer primary winding (252), wherein said headroom monitor (190) is configured to, based on the voltages present at the ends of the transistors (162, 184), generate a headroom signal representative of the headroom voltages at the transistors (162, 184). The variable DC power supply assembly includes a processor (80) to which the headroom signal from said headroom monitor (190) is applied and said variable power supply assembly is configured to, based on the headroom signal, set the level of the DC voltage applied to the center tap of the transformer primary winding (252) so that saturation voltages are applied to the transistors (162, 184).
