Abstract

The charging systems for mobile devices that support Wireless Power Transfer technology are under consideration. Most popular wireless charging standards are used and on this basis effective prototype is realized. Power Transfer Efficiency of the two-stage prototype is no worse than 60–70% at distances of 15–20 cm. The measurements of emitted magnetic fields are presented.
