Supply apparatus and method for supplying an electromedical instrument

Abstract

Supply apparatuses and methods for supplying an electromedical instrument with electrical energy are disclosed. For example, an adjustable and/or selectable operating mode parameter (M) defines an operating mode voltage (UM) that indicates a set point value for an electrode voltage (UE) at an electrode of the electromedical instrument. At a power supply output, an impressed output voltage (UA) is provided in accordance with a set point output voltage (US) as well as a variable output current (IA) for the electromedical instrument. In one as aspect, an operating mode voltage is corrected based on a correction value and/or voltage and forms a corrected operating mode voltage (UMC) based on which the set point output voltage (US) is provided for the power supply. The correction value or voltage are determined depending based on an actual value of the output current (IA) as well as an impedance parameter (ZI) that characterizes the impedance of the instrument.
