Wireless Power Transmitter Protection Using Receiver Energy Function

The system uses feedback from the Power Receiver's communications to monitor power transfer status. When the receiver sends an unexpected communication after exceeding energy requirements, the transmitter detects this anomaly and terminates power transmission, preventing overheating and damage while maintaining normal operation duration.

The communication signals between Power Transmitter and Power Receiver serve as an intermediary mechanism. By analyzing these communications, the transmitter can indirectly detect faults in the receiver's power transfer circuits without direct physical contact, enabling safe termination of power transmission when faults are detected.

The Power Receiver performs self-monitoring of its own energy requirements and transfer status, then communicates this information to the Power Transmitter. This self-service approach enables accurate fault detection without requiring complex monitoring equipment in the transmitter, as the receiver's own measurements are utilized.

The communication interface serves multiple functions: it coordinates power transfer, reports energy status, and enables fault detection. By making the communication system multi-functional, the patent avoids adding separate dedicated monitoring hardware, thus improving fault detection accuracy without significantly increasing system complexity.
