1. A method of treating live tissues by applying a high frequency electrosurgical signal thereto, comprising the steps of:

  • receiving an input sinusoidal voltage;

    generating repetitive pulses which are symmetrical in time with respect to and centered about peaks of the input sinusoidal voltage;

    applying the input sinusoidal voltage and the repetitive pulses to a high frequency generator to turn the generator on and off and generate bursts of high frequency signals which are centered about the peaks of the input sinusoidal voltage; and

    applying the signal bursts to an electrosurgical instrument.
