Abstract

An electrosurgical generator is disclosed that provides radio frequency electrical waveforms for performing surgical operations on a tissue mass. The various aspects of the present invention are embodied in an electrosurgical generator that includes a DC regulator (10), an amplifier (100), an energy recovery circuit (90), and a method of controlling these components to generate a desired electrical waveform for an electrosurgical operation.
