Claim 3:
4. Electrosurgical generator that is configured to implement a method according to claim 1, and to supply, during operation, a high-frequency alternating current to an electrosurgical instrument for plasma cutting of body tissue, wherein the electrosurgical generator has outputs for connecting an electrosurgical instrument to supply an electrosurgical instrument connected to the outputs during operation with a high-frequency alternating current, and for determining an impedance of a load connected to the outputs;
wherein the electrosurgical generator further features an impedance measuring unit and a voltage measuring unit as well as an output voltage control unit, of which
the output voltage control unit is configured to control or regulate an AC output voltage of the electrosurgical generator in accordance with a predefined maximum output voltage value, and
the impedance measuring unit is designed to determine an impedance of the load present at the outputs of the electrosurgical generator during operation;
wherein:
the output voltage control unit is designed to control the AC output voltage depending on a maximum output voltage value which, at least for part of an initial phase, is a different maximum output voltage value than during a subsequently occurring equilibrium phase.
