Efficiency Analysis of Wireless Power Transmission for Portable Electronics
School of Electrical Engineering, Chongqing University, Chongqing, China
With the portable electronics becoming more and more popular, a model of wireless power transmission for general portable electronics was presented based on the principles of magnetic resonance transmission. And that transferring the model to an equivalent circuit was possible to calculate. The characteristics of the system and the optimal conditions were analyzed, and the influence of the transmission efficiency for the Coupling factor and the Quality factor was discussed. The theory analysis and simulation in MATLAB show that the performance of the system can be optimized by adjusting the coupling factor between the transmitter coupling coils. Furthermore, the feasibility of this theory was proven by experiments. Thus, this paper provides a useful reference to improve the wireless power transmission for portable electronics.
Key words: portable electronics / wireless power transmission / magnetic coupling resonance / efficiency
