Transceiver Assembly for Free-Space Power Transmission and Data Communication Systems

Abstract

To provide a transceiver assembly for free space power transfer and data communication using laser light in a wireless power transfer system.SOLUTION: In a transceiver assembly, a photodiode assembly 62 of a receiver 60 receives a high-power laser beam from a transmitter and converts the high-power laser beam into an electrical energy. A voltage converter 64 adjusts an input impedance based on a voltage measurement of the photodiode assembly 62 to maximize a power transfer from the photodiode assembly 62 to an energy storage device 65 electrically coupled to the voltage converter 64. An IR LED 78 and an IR communication photodiode 76 are in free space optical communication with the transmitter. The IR LED 78 sends a signal indicating the presence and a location of the transceiver to the transmitter at least when the energy storage device 65 requires charging.SELECTED DRAWING: Figure 3
