WIRELESS CHARGING DEVICE Russian patent published in 2016 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering. Wireless charging device consists of a charging station and a receiving device, capable of converting alternating magnetic field into electric current, which is used for charging batteries of mobile electric current consuming devices. Receiving device is embedded in mobile device consuming electric current. Electric coil with ferromagnetic core of inductor of charging station is wound in two isolated and not electrically connected to each other conductors. Such design of the inductor of charging station involves connecting one of the conductors to external alternating-current mains and generates alternating magnetic field, and the second conductor, being in alternating magnetic field, generates alternating current, which is used as an external source of electric energy for the next charging station. Since inductor of charging station is an electromagnet with two poles, both planes of charging station are used.

EFFECT: technical result consists in providing wireless charging of several mobile devices using several cascade connected charging stations in the presence of one external AC source.
