The invention discloses a high-performance wireless charging device. In order to overcome the shortcomings such as large magnetic loss of electromagnetic space, large coil size, high material consumption, low production efficiency and high cost of an existing wireless charging device, the cross section of a winding material of a coil of the high-performance wireless charging device is in a shape of non-circular rectangle or square; since winds wound by the winding material are positioned on a same plane and of consistent interval specifications, each coil winding is a coiled body comprising a plurality of flat sheet-like winds which are positioned on the same plane and of consistent interval specifications, and the coil winding can be integrally formed. The high-performance wireless charging device is mainly applied to wireless charging in the field of electric vehicles and intelligent mobile phones. Experiment shows that the space magnetic loss rate of the high-performance wireless charging device is decreased by 85%, the receiving and transmitting efficiency is improved by 20%, and defective ACR can be avoided; and the coil is small in size, occupies small space, can be formed by using a mold without manual or mechanical winding, and is low in material consumption, high in production efficiency and low in production costs, thereby significantly improving the benefit.
Description
technical field [0001] The invention relates to a device mainly used in the field of electric vehicles and smart phones for wireless charging using the principle of electromagnetic induction, specifically a high-performance wireless charging device. Background technique [0002] The wireless charging device uses the electromagnetic induction of the wireless charging coil (transmitting coil TX) to charge, and is used in fields such as electric vehicles and smartphones. [0003] Wireless charging realizes secondary energy conversion, that is, after the grid power is stepped down (or directly) into DC, a higher frequency switch is performed to control the AC exchange output. [0004] The deficiencies of the existing wireless charging device, firstly, high-power AC-DC-AC current conversion for secondary wireless transmission, the electromagnetic space magnetic loss rate is large; secondly, the coil of the existing wireless charging device is wound with self-adhesive enameled wir...
