Abstract:
The present invention provides a method and an apparatus for controlling the wireless induction power supply. The apparatus comprises a transmitter control circuit and a receiver control circuit. The method comprises generating a plurality of switching signals for switching a transmitter winding and generating a power; detecting a level of a transmitter signal from the transmitter winding; and controlling a switch to deliver the power from a receiver winding to a load. The receiver winding is coupled to receive the powerfrom the transmitter winding. The switching signals will be disabled if the level of the transmitter signal is not higher than a threshold over a first period or the level of the transmitter signal is higher than a high-threshold over a second period. Accordingly, the method and the apparatus according to the present invention have the foreign object detection (FOD) function for the safety.

Claim (Index 32):
A method for a wireless induction power supply, comprising:\n generating a plurality of switching signals for switching a transmitter winding and generating a power for delivery to a load wherein the plurality of switching signals are generated by a transmitter circuit; and the transmitter circuit detecting a foreign object and disabling the plurality of switching signals in response to detecting an impedance of the transmitter winding being less than a threshold while power is not delivered to a load and while the plurality of switching signal are enabled, and the transmitter circuit detecting a no-load condition and disabling the plurality of switching signals in response to the impedance greater than the threshold over a period while the plurality of switching signal are enabled.
