FOREIGN OBJECT DETECTION DURING WIRELESS POWER TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097501 titled 'FOREIGN OBJECT DETECTION DURING WIRELESS POWER TRANSMISSION
Simplified Explanation
A wireless power transmitter is designed to transfer power wirelessly to a receiver through magnetic coupling. The transmitter includes a power transfer coil, a power converter, and control and communications circuitry.
- The wireless power transmitter includes a wireless power transfer coil that magnetically couples with a corresponding coil in the receiver to transfer power wirelessly.
- The power converter in the transmitter is responsible for driving the wireless power transfer coil.
- Control and communications circuitry in the transmitter is connected to the power transfer coil and the power converter. It operates the power converter to transfer power to the receiver based on a negotiated power transfer agreement.
- The control and communications circuitry also sends a polling signal during power transfer to detect foreign objects, such as wireless transponders, and can reduce or stop power transfer upon receiving a response from a foreign object.
Potential Applications
This technology can be applied in various industries such as consumer electronics, automotive, medical devices, and industrial automation for wireless charging applications.
Problems Solved

Original Abstract Submitted
a wireless power transmitter can include a wireless power transfer coil designed to magnetically couple with a corresponding coil in a wireless power receiver to facilitate wireless power transfer from the wireless power transmitter to the wireless power receiver, a power converter configured to drive the wireless power transfer coil, and control and communications circuitry coupled to the wireless power transfer coil and the power converter. the control and communications circuitry can be configured to operate the power converter to drive the wireless power transfer coil so as to transfer power to the wireless power receiver in accordance with a negotiated power transfer. simultaneously during power transfer, the control and communications circuitry can send a polling signal to detect a foreign object including a wireless transponder and reduce or stop wireless power transfer upon receiving a response to the polling signal from a foreign object including a wireless transponder.
