Abstract
Ideally, the power output of electrosurgery units must be kept constant during its utilization despite the many differences in the resistance of tissues and the anatomic features of the patients being operated on. The aim of this paper is to present a method of designing the control stage of a high frequency electrosurgery equipment considering the adequate choice of passive components to reduce the variation of the power source voltage. The design focused on the automatic regulation of the average power output. The results obtained demonstrate that by using a simulation approach it is possible to predict the response of the electrosurgery unit output as a means to better regulate it.
