Abstract: The disclosure provides an example electrosurgical system and methods for use thereof. The electrosurgical system includes a high-frequency inverter (“HFI”) having a full bridge and a control system electrically coupled to the HFI. The control system controls output parameters including one or more of an output power Pout(t) and an output voltage or current by varying power reference Pref(t) or switch states of the HFI. The control system causes a power adaptation ?P(t) to a preset power set Pset based on receiving at least one of impedance feedback and thermal feedback according to the following relationship: Pref(t)=Pset+?P(t).
