AI Technical Summary
Technical Problem
Existing wireless charging systems are limited by the inability to charge devices at rotated angles, restricting charging freedom and convenience.
Method used
A transmitter module with two wireless transmitters excited to transmit with a frequency difference, enabling non-coherent combining at a receiver module, which allows for omnidirectional wireless charging without active control.
Benefits of technology
Enables positional- and rotational-free wireless charging by ensuring non-zero time-averaged transfer power at any random receiver rotation angle, eliminating blind spots and providing constant high efficiency and output power.
