The electrosurgical generator according to the invention includes an oscillating circuit excited by means of an excitation circuit having a frequency preferably close to its resonant frequency, wherein the oscillation should be periodically interrupted. This can be done, for example, in situations where a pulse-pause modulation of a radio frequency voltage must be created, the fundamental frequency of which, for example, 350 kHz or 500 kHz, can be modulated with a modulation frequency of, for example, 50 kHz.
