William J Bowers, Phillip D Hardwick: Electrosurgical generator with high-frequency pulse width modulated feedback power control. C R Bard, John R Ley, March 1, 1988: US04727874 (316 worldwide citation)

A pulse width modulation technique regulates the output power of each cycle of a radio frequency surgical signal of an electrosurgical generator. The delivered power of the surgical signal is determined by multiplying the sensed current and the sensed voltage of the surgical signal. An error signal ...
