Abstract

Mobile devices get highly developed recently, but the energy supple of mobile devices still need to be optimized. This paper investigates wireless power transfer for mobile applications. The energy supplied by DC source is transferred through primary coil to the secondary coil using the principle of electromagnetic induction. A novel inductance structure is adopted at the primary coil to improve the quality factor of primary coil in a large range. The Q value of the primary coil used this novel structure can reach more than 600, and the overall efficiency can reach 75%. The maximum power transmission distance can reach 9cm at a resonant frequency of 104 KHz and more than one device can be charged for a multiple switch unit is implemented in primary subsystem. This research can make people charging more convenient, save the charging time when there are more than one mobile devices.
