A generator with a regeneration device. 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. To stop the oscillation in the generator's oscillating circuit as abruptly as possible without losing the energy stored in the oscillating circuit, a regeneration circuit is provided, implemented by means of a voltage multiplier circuit. Compared to a boost converter coupled inductor, it has the advantage of providing a low capacitive load to the oscillating circuit, especially because it is only electrically effectively connected to the oscillating circuit via a switch during the regeneration phase. This concept allows for efficient energy regeneration and therefore allows for precise amplitude modulation of the radio frequency voltage, particularly square wave modulation (on-off-switch).
