title = "Development of New Wireless Charging System with Improved Energy Efficiency for Electric Vehicles",
abstract = "In this paper, a new wireless charging system with improved energy efficiency for electric vehicles was proposed and simulated by improving efficiency of power conversion through magnetic inductive coupling or magnetic resonance coupling. The relationships between the position of receiver and the magnitude of wireless transfer system were first investigated. The number of turns with different coil structure were also discussed as it can affect the power efficiency. A new method by introducing various number of magnetic bars under coils configuration and shaping magnetic flux is proposed and demonstrated to achieve higher power efficiency. Simulation of this method was conducted to initiate mutual inductance of transmitter and receiver coils. The performance of new methods were simulated in MATLAB and COMSOL in order to compare with the old method. An energy efficiency of 82.5 \% with an improvement of 7.45 \% was achieved.",
