Various embodiments of a wireless connector system are described. The system has a transmitter module and a receiver module that are configured to wirelessly transmit electrical energy and/or data via near field magnetic coupling. The wireless connector system is designed to increase the amount of wirelessly transmitted electrical power over a greater separation distance. The system is configured with various sensing circuits that alert the system to the presence of the receiver module to begin transfer of electrical power as well as undesirable objects and increased temperature that could interfere with the operation of the system. The wireless connector system is a relatively small footprint that is designed to be surface mounted.

Wireless connector system

A dual wireless power transfer system is disclosed having an input power supply providing power at a first voltage Vand a first wireless power transmission system receiving power at a first power input from the input power supply, the first wireless power transmission system including a first transmitter antenna and a first driver for driving the first transmitter antenna for wireless power transmission to a first wireless receiver system and wireless receipt of data from the first receiver system, wherein data wirelessly received at the first transmitter antenna from the first receiver system at least partially feeds back onto the first power input. A second wireless power transmission system includes a second transmitter antenna and a second driver for driving the second transmitter antenna for wireless power transmission to a second wireless receiver system. A low voltage drop out receives power from the input power supply at Vand provides power at a preselected lower voltage Vto the second wireless power transmission system, such that Vis independent of data received at the first transmitter antenna.

Cross talk and interference mitigation in dual wireless power transmitter

The present application relates to an apparatus which comprises a wireless power transfer (WPT) system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference (EMI), and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage. Other features might include integration of an antenna and a battery within one module.
