Inductive Transmission System

Patent No. EP2266123 (titled "Inductive Transmission System") was filed by Powermat on Dec 18, 2008. The application was issued on Sep 11, 2024.

Inductive power transfer system for wireless power delivery that eliminates the need for conductive connections between the power source and load. The system employs a unique architecture where the power source and load are connected through a resonant inductor pair, with the power source generating a periodic low-energy power pulse. This pulse is transmitted through the resonant inductor to the load, where it induces a controlled current flow. The system incorporates a passive transmission lock mechanism that automatically detects the presence of the load coil and initiates the power transfer process. The power transfer process is controlled by a separate set of switching signals that are drawn from the power source terminals, enabling efficient and reliable wireless power transfer.
