High frequency leakage current prevention device for electrosurgery equipment

摘要

the device has a compensation circuit for generating a compensation current (IK) for at least the partial compensation of a leakage current (IF) at the neutral electrode (NE) of the surgical device. This also has an active electrode (AE) and a generator (UHF). A compensation voltage generator (UK) is connected to the neutral electrode on one side, and to earth potential is connected on the other side. A compensation capacitor (Ck) is connected between the compensation voltage source and the earth potential.
