Abstract
A method of improving efficiency of an electrosurgical generator is presented, the method including controlling an output of an electrosurgical generator by converting a direct current (DC) to an alternating current (AC) using an inverter, and sensing a current and a voltage at an output of the inverter. The method further includes the steps of determining a power level based on the sensed voltage and the sensed current, determining an efficiency of the electrosurgical generator, and inserting a predetermined integer number of off cycles when the efficiency of the electrosurgical generator reaches a threshold power efficiency.
