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 24):
A method for a transmitter circuit of a wireless induction power supply, comprising:\n configuring a transmitter control circuit to form one or more switching signals for switching a transmitter winding of the wireless induction power supply and generating a power for delivery to a load by a receiver circuit of the wireless induction power supply; configuring an input of the transmitter control circuit to receive a transmitter signal formed by the transmitter winding in response to the one or more switching signals wherein the transmitter signal is representative of an impedance of the transmitter winding; and configuring the transmitter control circuit to detect a foreign object and disable the one or more switching signals in response to detecting the transmitter signal changing to a level that is representative of the impedance being less than a threshold value while the one or more switching signals are enabled and the load is decoupled from receiving the power, the transmitter control circuit continuing to enable the one or more switching signals in response to detecting the level of the transmitter signal changing to be representative of the impedance being greater than the threshold while the load is decoupled from receiving the power and the one or more switching signals are enabled, and the transmitter control circuit detecting a no-load condition and disabling the one or more switching signals in response to detecting the level representative of the impedance being higher than the threshold over a first period while the load is coupled for receiving the power and the one or more switching signals are enabled.
