PROBLEM TO BE SOLVED: To provide an electrosurgical system for operating an electrosurgical generator.SOLUTION: A generator 200 includes: RF output stages 230, 232 constituted so as to generate at least one electric surgery waveform including a plurality of cycles; at least one sensor 280 connected to the RF output stages 230, 232 constituted so as to measure voltage and current of the at least one electric surgery waveform; and a controller 224 connected to the at least one sensor 280 and the RF output stages 230, 232. The controller 224 has a proportionality-integration-differentiation controller having at least one of a voltage limiter or current limiter. The proportionality-integration-differentiation controller is constituted so as to saturate the RF output stages 230, 232 on the basis of voltage-current characteristics of the RF output stages 230, 232. |
