適用於滑鼠暨行動裝置無線充電計費系統之設計

Abstract

The target of this work is to design a wireless power transfer system and use it on mouse power supply and a fee-counting function for mobile device charging. The main structure of this research is resonance magnetic field energy transmission, which is based on “Wireless Power Transfer via Strongly Coupled Magnetic Resonances”. The system includes a beacon power saving solution and battery charging credit verify by internet database concept. Furthermore it also implements a self-coupled frequency correction function with a voltage controller oscillator. In the work, the wireless power transfer technique is also used in wireless mouse power supply and mobile device battery charging. Experimental results show that the basic characteristics of resonance magnetic field power transmission and the functions of the circuit system design in this paper are provided for verification. The charging controlled by input a credit code and check through an internet connection to implement a fee-counting function. Finally, the maximum wireless power transfer efficiency is about 22.82 %, and the maximum wireless power transfer distance is up to 9 cm when the secondary power is about 183 mW in our design.
