         21 . A method of providing power to an electrosurgical instrument comprising:
 generating a non-sinusoidal driving voltage having a substantially constant driving frequency;   providing the non-sinusoidal driving voltage to an LC circuit having a resonant frequency of substantially twice the substantially constant driving frequency;   generating a quasi-sinusoidal current in the LC circuit from the non-sinusoidal driving voltage; and   providing the quasi-sinusoidal current to an electrical output, wherein the electrical output is configured for coupling to an electrical input of a surgical instrument.
