| titleOfInvention | Above resonance frequency operation for wireless power transfer |
| abstract | A wireless power transmission system includes a primary circuit and a secondary circuit, which are coupled through coupling coils. The primary circuit includes an alternating current (AC) power supply source that provides an alternating current signal through a series connection of a primary capacitor and a primary coil. The secondary circuit includes a parallel connection of a secondary coil, a secondary capacitor, and a load. The resonance frequency f0 of the wireless power transmission system is a frequency at which the power transfer efficiency of the wireless transmission system achieves a maximum for an infinitesimally small resistive load. The operational frequency of the AC power supply source is selected to be above the resonance frequency f0 so as to provide greater efficiency and/or greater power transfer rate in the presence of a finite impedance load. |
