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).

Abstract: Apparatus for conditioning power generated by an energy source includes an inverter for converting a DC input voltage from the energy source to a square wave AC output voltage, and a converter for converting the AC output voltage from the inverter to a sine wave AC output voltage.

Abstract: A novel power conditioning converter which provides a significant reduction in input current ripple (<1%), with efficiency above 90% and reduced thermal management is proposed. The converter in discussion has a sort-switched, multilevel, high frequency converter, which acts as an interface between the dc/dc boost and the ac/ac converter. This paper presents a detailed description of the operation of the converter and highlights the important features and advantages. SABER simulation results are presented to provide an improved understanding of the switching mechanisms. A discussion on the implementation of the converter and the status of ongoing work is presented.
