Classification: CPC A  H | IPC A

Claim 14:
15. A digital closed-loop control system for use with an electrosurgical generator that supplies electrosurgical RF energy to a surgical site, the digital closed-loop control system comprising:
a feedback system for continually monitoring electrical properties of the supplied RF energy to the surgical site as a concurrent surgical condition and generating digital RF signals relating thereto; and
a microcontroller, responsive to the generated digital RF signals from the feedback system, is configured with a variable gain factor to regulate and control an RF amplifier that generates the supplied RF energy across a plurality of RF resolution settings and a plurality of RF regulation modes, wherein the microcontroller is further configured to:
select one of the plurality of RF regulation modes based on individual error values calculated for each of the plurality of RF regulation modes; the RF regulation mode being selected based on a most positive error value, and
generate an accumulated error value over time, for the selected RF regulation mode, using an integrator module that includes a variable gain calculator.
