Abstract
An electrosurgical system includes an RF output stage configured to impart RF power between first and second electrodes; measurement circuitry measures current and voltage imparted between the first and second electrodes; a processing circuit calculates power and impedance, based upon the measured current and the measured voltage; the processing circuitry uses a proportional-integral-derivative control loop to control RF power imparted between the electrodes, based upon a selected one of the measured current, the measured voltage, calculated power, and the calculated impedance.
