An electrosurgical generator is contemplated by the present disclosure. The generator applies 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 generator also measures 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 half-cycles and the peak voltage of the negative half-cycles to determine generation of electrical discharges. The generator further adjusts 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.
