Inductive Power Supply

Patent No. EP2481141 (titled "Inductive Power Supply") was filed by Powerkiss on Sep 22, 2010. The application was issued on Apr 3, 2024.

Patent Summary

Wireless power transfer system for inductive power supplies that enables efficient power delivery to mobile devices through an inductive link. The system utilizes an inductive link between the primary and secondary coils to transfer power while maintaining precise control over the output voltage. The link enables continuous power transfer from the primary coil to the secondary coil, eliminating the need for separate regulators and enabling real-time load monitoring. The system employs load sensing through capacitive measurement to detect changes in the secondary coil's load, and the power signal is modulated using Load Shift Keying (LSK) to optimize power transfer based on the load condition.
