Investigation of High-Efficiency for Smartphone Applications

Abstract

Wireless Power Transfer (WPT) technology has recently become popular, due to its many benefits, including its simplicity, safety, dependability, absence of cables, etc. Many researchers are working to advance this technology so that it can be used in future smartphones. In this research paper, a wireless smartphones charger has been designed and simulated using MATLAB program to charge a smartphones device with acceptable frequency and efficiency, also with acceptable power approximately 10 watt above or below at different frequencies, in this paper a 70–100KHz is used. WPT classified into two categories first is the far field type which is used for the long distance and the second one is the near field type which is used with small and medium distance such as the smartphone charging that had been discussed. The results in this paper is discuss the effect of different frequencies on the efficiency of the charging system using magnetic resonance coupling technique.
