Claim:
1. A wireless power transmission system for providing an alternating current (AC) line frequency to a load, comprising: a line frequency rectifier that rectifies a source AC line frequency; a direct current (DC)-to-AC inverter that inverts the rectified AC line frequency to an envelope modulated high frequency AC with an amplitude that varies continuously in a half-sinusoidal fashion at a line frequency rate; a resonant air gap wireless transmission transformer that transmits the envelope modulated high frequency AC; a high frequency rectifier that rectifies the transmitted envelope modulated high frequency AC; a high frequency ripple filter that filters the rectified high frequency AC into a rectified line frequency AC; and a polarity inversion circuit that inverts every other half cycle of the rectified high frequency AC so as to create a line frequency sinusoidal voltage waveform for application to the load as the AC line frequency.
