Abstract
An electrosurgical high frequency (HF) generator comprising a generator circuit that produces an HF current between an active electrode and at least one neutral electrode. During the cutting or coagulating of biological tissue, unwanted tissue heating due to the HF current can be reduced because the electrosurgical HF generator comprises at least one further auxiliary neutral electrode connected in parallel to the neutral electrode.
