Abstract
A method for controlling an electrosurgical generator is contemplated by the present disclosure. The method includes applying an electrosurgical waveform to tissue through an electrode. The electrosurgical waveform includes one or more positive half-cycles one or more negative half-cycles. The method also includes measuring voltage and current of the electrosurgical waveform to detect a peak voltage of each of the positive half-cycles and the negative half-cycles and comparing the peak voltage of the positive half-cycles and the peak voltage of the negative half-cycles to determine generation of electrical discharges. The method further includes adjusting the current of the electrosurgical waveform to regulate the generation of the electrical discharges based on a comparison of the peak voltage of the positive half-cycles and the peak voltage of the negative half-cycles.
