Circuit and method for controlling an electrosurgical generator using a full bridge topology
First Claim
1. A system for controlling an electrosurgical generator using a full bridge topology, comprising:
- a high voltage direct current power source which supplies power;
a radio frequency output stage which receives power from the high voltage direct current power source and outputs radio frequency energy at a predetermined radio frequency set point;
at least one sensor which determines at least one parameter of the radio frequency energy being applied to a load; and
a microprocessor configured to receive the at least one parameter of the radio frequency energy and output the predetermined radio frequency set point to the radio frequency output stage as a function of the at least one parameter of the radio frequency energy.

Abstract
A system for controlling an electrosurgical generator using a full bridge topology is disclosed. The system includes a high voltage direct current power source which supplies power and a radio frequency output stage which receives power from the high voltage direct current power source and outputs radio frequency energy at a predetermined radio frequency set point. The system also includes one or more sensors which determine one or more parameters of radio frequency energy being applied to tissue and a microprocessor configured to receive one or more parameters and outputs the predetermined radio frequency set point to the radio frequency output stage as a function of one or more of the parameters of radio frequency energy.
