电外科谐振逆变器的功率控制系统和方法
摘要：
本发明涉及电外科谐振逆变器的功率控制系统和方法。公开一种电外科发生器。该发生器包括：RF输出级，其配置为产生包括多个周期的至少一个电外科波形；耦合到所述RF输出级的至少一个传感器，所述至少一个传感器配置为测量所述至少一个电外科波形的电压和电流；以及控制器，其耦合到所述至少一个传感器和所述RF输出级，所述控制器包括具有电压限制器或电流限制器中的至少一个的比例‑积分‑微分控制器，所述比例‑积分‑微分控制器配置为基于所述RF输出级的电压‑电流特性使所述RF输出级饱和。
摘要（英）：

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.
