A new dual current-mode controller produces a fast, accurate constant-power high-frequency ac output, with maximum current and voltage limits for an electrosurgical generator. The regulation of ac output power is achieved with near-deadbeat control, without measurement or feedback of the output voltage or current. Compared to existing technology, the prototype generator reduces unintended tissue damage by significantly improving regulation of output power, while reducing complexity and parts count.
一种新的双电流模式控制器可产生快速、准确的恒功率高频交流输出,并为电外科发生器提供最大电流和电压限制。交流输出功率的调节采用近乎无过冲控制,无需测量或反馈输出电压或电流。与现有技术相比,该原型发生器通过显著改善输出功率调节,同时降低复杂性和部件数量,从而减少意外的组织损伤。
