摘要：
An electrosurgical generator may reduce unintended tissue damage by improvingregulation of output power. The electrosurgical generator may control thepower during acycle, and react to a change in power if arcing occurs. Voltage sources,especially,demonstrate the tendency to have large, uncontrolled power excursions duringnormalelectrosurgical use. The magnitude of the power excursions may be dependent onvariousfactors. An exemplary electrosurgical generator control scheme reduces orminimizes thethermal spread by accurately supplying the specified power within a fewcycles.Additionally, fast and accurate regulation provided by the constant voltagemode reduces orminimizes unintentional tissue charring. Thus, reduced thermal spread andcharring shouldresult in better surgical outcomes by reducing scarring and decreasing healingtimes. Anelectrosurgical generator controller may be configured to control both a DC-DCbuckconverter and a DC-AC boost inverter based in part on electrical parameters oftheelectrosurgical generator.
