1. A control circuit that controls a variable output signal to electrodes used in electrosurgical procedures, the control circuit comprising:

  • (a) a DC power supply circuit that provides regulated low voltage and high voltage outputs; and

    (b) a radio frequency (RF) waveform generator circuit that provides pulse duration modulation of a carrier signal, the carrier signal directly affecting the variable output signal to the electrodes, the RF waveform generator circuit generating a plurality of different user selectable waveforms based on the pulse duration modulation of the carrier signal.
