Abstract
A wireless power supply and power receiving device includes a sensor, a control module, a coil module and a rectifying and switching module. The control module determines a position or a direction of the wireless power supply and power receiving device according to the sensor, and the rectifying and switching module selectively operates in a wireless power supply mode or a wireless power receiving mode according to the position or the direction. When in the wireless power supply mode, the rectifying and switching module converts the power energy to wireless power energy to provide power to a first external device by using the coil module. When in the wireless power receiving mode, the rectifying and switching module receives wireless power energy from a second external device via the coil module.
