MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202614006316 A) filed by Erbe Elektromedizin Gmbh on January 22, 2026, for Supply Apparatus And Method For Supplying An Electromedical Instrument.
Inventors include Weiler, Rolf; and Philipp Maier.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention refers to a supply apparatus (11) and a method for supplying an electromedical instrument (12) with electrical energy. An adjustable and/or selectable operating mode parameter (M) defines an operating mode voltage (UM) that indicates a set point value for an elec-trode voltage (UE) at an electrode (15, 16) of the electro-medical instrument (12). At a power supply output (24) of a power supply (23) of supply apparatus (11) an impressed output voltage (UA) is provided in accordance with a set point output voltage (US) as well as a variable output cur-rent (IA) for the electromedical instrument (12). Due to the impedance of instrument (12), a reactive voltage can be created in the electrical path to the electrode (15, 16), so that the electrode voltage (UE) does not correspond to the desired operating mode voltage (UM). For this rea-son, the operating mode voltage is corrected based on a correction value (C) and particularly a correction voltage (UC) and forms a corrected operating mode voltage (UMC) based on which the set point output voltage (US) is provid-ed for the power supply (23). The correction value (C) or correction voltage (UC) are determined depending on an ac-tual value of the output current (IA) as well as an imped-ance parameter (ZI) that characterizes the impedance of the instrument (12).
