Design of the Power Control System of the Electrosurgical Generator Based on 80C552

A power control system of the electrosurgical generator based on 80C552 micro-controller is introduced to solve the problem of output power fluctuation.Two levels control is adopted,separately controlling the work voltage of adjusting power amplifier circuit and driving pulse signals of commanding power amplifier circuit,of which the first one contains compensation to AC voltage fluctuation.The experiment result shows that the power control system performs better.
