Surgical tool power console comprising a transformer with a built-in current source to generate a matching current that cancels the parasitic capacitance
A power surgical tool control console (50) comprising a transformer (250) having a secondary winding (264) from which a tool drive signal is generated. Also located in the transformer is a matched current source consisting of a leakage control winding (246) and a capacitor (248). The current supplied by the matching current source at least partially cancels any leakage current that may be present.工具駆動信号が生じる二次巻線（２６４）を有する変圧器（２５０）を備える電動式外科工具用制御コンソール（５０）。変圧器内には、漏れ制御巻線（２４６）及びコンデンサ（２４８）から成る整合電流源も配置されている。整合電流源によって供給される電流は、存在し得る漏れ電流を少なくとも部分的に相殺する。
