Abstract: Example embodiments are disclosed for detecting the proximity of a user to a wireless charger and switching off or gradually reducing the power applied to the transmitting coils as long as the user is closer than a threshold distance. In embodiments, a power source circuit in a wireless charging device is configured to produce a source alternating current. A transmitting coil is configured to magnetically couple with a proximately located receiving coil in a user's device, using contact-less electromagnetic induction, to wirelessly provide power to the receiving coil. A power control circuit is coupled between the power source and the transmitting coil, having a control input configured to control power delivered from the power source to the transmitting coil.
