Abstract

An electrosurgical generator with a high-voltage power supply that supplies a DC output voltage receives the DC output voltage of the high-voltage power supply and generates a high-frequency AC output voltage. When generator is operating, a control unit receives signals from an AC output voltage measuring unit and current measuring unit. The control unit limits an increase of DC output voltage of the high-voltage power supply as soon one predefined maximum value is reached or exceeded. When the generator is operating, the control unit configured to receive signals from a DC output voltage measuring unit that represent a respective current value of the DC output voltage, and to compare a respective current value of DC output voltage with a predefined minimum value for DC output voltage, and to cause the DC output voltage of the high-voltage power supply to increase as soon as it falls below the predefined minimum value.
