Photovoltaic power transfer system and methods

Abstract

The present invention involves a bimodal near-field resonant wireless system for transferring power from one or more photovoltaic cells to a power load. One or more transmission modules are in electrical communication with the one or more photovoltaic cells, converting power from photovoltaic cells into an oscillating electrical power signal having a variable oscillation frequency. Transmitter resonators are in electrical communication with transmission modules resonating at the variable oscillation frequency. Receiver resonators, resonating at the variable oscillation frequency and disposed to bimodally receive power from transmitter resonators simultaneously via capacitive coupling and magnetic induction according to an adjustable transfer mode ratio of capacitive to inductive power transfer. Receiver modules are in electrical communication with receiver resonators, each receiving power from receiver resonators and render power received from receiver resonators into a direct current voltage, and transmit the direct current voltage to the power load.
