Abstract
A system for minimizing neuromuscular stimulation includes a converter, an inverter, and a controller. The converter is configured to output a dc waveform and includes at least one first switching element operated at a first duty cycle. The inverter is coupled to the converter and includes at least one second switching element operated at a second duty cycle. The inverter is configured to invert the DC waveform to generate an electrosurgical pulse waveform. The controller is coupled to the converter and the inverter, and is configured to control the first duty cycle to adjust a magnitude of the electrosurgical pulse waveform and the second duty cycle to adjust at least one property of the electrosurgical pulse waveform to minimize neuromuscular stimulation.
