Until now, ohmic consumers have been used to abruptly complete the output signal in RF surgical generators. Considering an RF surgical generator comprising a power supply with at least one storage capacitor and a controllable switching device with at least one energy storage device (e.g., a transformer) by which an RF output signal that can be delivered to an RF surgical instrument is generated, it is suggested herein that a regenerative device be provided between the energy storage device and the storage capacitor. Furthermore, a control mechanism is used for controlling the switching device and the regenerative device such that, if the RF output signal is to be completed, the regenerative device is energized for at least part of the time, and the energy storage is at least partially discharged in the storage capacitor.
