ELECTROSURGICAL GENERATOR |
摘要 |
An electrosurgical generator which provides a constant power output particularly suited for cutting arc formation at an active electrode which exhibits a dynamic active surface area of varying geometry. Essentially constant power-based control is achieved through the utilization of a d.c. link voltage the level of which functions to establish the amplitude of the output of an RF resonant inverter. A dual loop feedback control is described wherein output power based control signals are slowly introduced at low gain , while link voltage based controls are comparatively rapidly applied. Enhance d development of a controlling d.c. link voltage is achieved through the utilization of an input network incorporating a power factor correction stag e.
