Abstract
A wireless power transmission circuit for wirelessly transmitting line frequency sinusoidal AC power to a load where the line frequency ripple filter of conventional circuits is eliminated and a DC-to-AC inverter is replaced by a simple polarity inversion circuit. The envelope of the high frequency AC on the AC line frequency source side is not constant but varies continuously in a half-sinusoidal fashion at the line frequency. Wireless transmission occurs only with a half-sinusoidal, constantly varying envelope, not the constant amplitude envelope of prior art. High frequency rectification and high frequency ripple filtering occurs as in the prior art but the ripple filter time constant is selected so that resulting waveform is an accurate replica of the rectified line frequency voltage present on the transmitter side. A polarity inversion stage replaces the DC-to-AC inverter of conventional art to generate the line frequency AC.
