1. A method of controlling output power of an electrosurgical generator apparatus that controls a variable output signal to a pair of electrodes, the method comprising:

  • (a) setting the output power of the generator apparatus to a selected power output level;

    (b) measuring an impedance across the electrodes using an impedance monitoring circuit when the electrodes are applied to an area of tissue;

    (c) changing the output power of the generator apparatus to a boost power output level greater than the selected power output level, the boost power output level corresponding to a calculation based at least in part on the measured impedance;

    (d) applying the output signal to the electrodes at the boost power output level for a first time duration; and

    (e) changing the power of the output signal applied to the electrodes to the selected power output level after the first time duration.
