Abstract
In accordance with some embodiments of the present invention, an ion cooling engine (ICE) controlled by a transmitting or receiving device cools a transmit or receive coil and possibly other parts of a wireless power transmitter or receiver system. In some embodiments, the ICE includes a low-voltage circuit controlled by the transmitting device and coupled to a high voltage circuit that generates the airflow. Other features are also provided.
