摘要:
An electrosurgical generator is disclosed. The generator includes an RF output stage configured to generate at least one electrosurgical waveform including a plurality of cycles; at least one sensor coupled to the RF output stage, the at least one sensor configured to measure a voltage and a current of the at least one electrosurgical waveform; and a controller coupled to the at least one sensor and the RF output stage, the controller including a proportional-integral-derivative controller having at least one of voltage limiter or a current limiter, the proportional-integral-derivative controller configured to saturate the RF output stage based on voltage-current characteristics of the RF output stage.
