Zusammenfassung:SYSTEM AND METHOD FOR POWER CONTROL OF ELECTROSURGICAL RESONANT INVERTERS An electrosurgical generator (200) is disclosed. The generator (200) includes an RF output stage configured to generate at least one electrosurgical waveform including a plurality of cycles; at least one sensor (280) 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 (224) coupled to the at least one sensor (280) and the RF output stage, the controller (224) 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.
