Abstract
A HF surgery device had a microprocessor and a comparator which in combination generate a control signal which acts on a rectified operating voltage, which drive a HF generator. The HF generator can be modulated with a modulation signal. In order to automatically maintain the effective output power at a constant level in the event of a modulation of the HF generator, the microprocessor forms a reference value from the modulation signal and from a prescribed setting signal for setting a HF output power. The reference value is compared to the operating voltage in the comparator for forming the control signal.
