Abstract
An electrosurgical generator is presented including a radio frequency (RF) amplifier coupled to an electrical energy source and configured to generate electrosurgical energy, the RF amplifier including an inverter configured to convert a direct current (DC) to an alternating current (AC), and a plurality of sensors configured to sense voltage and current of the generated electrosurgical energy. The electrosurgical generator further includes a controller coupled to the RF amplifier and the plurality of sensors. The electrosurgical may be further configured to determine a power level based on the sensed voltage and the sensed current, determine an efficiency of the electrosurgical generator, and insert a predetermined integer number of off cycles when the efficiency of the electrosurgical generator reaches a threshold power efficiency.
