A study on the magnetic resonant wireless charging system for electrical vehicles

摘要

In this paper, a magnetic resonant wireless power transmission of charging system for electrical vehicles is proposed. Given that world's trend of wireless power transmission, it is adequate to select a resonant frequency 20kHz. A diameter of this system is 30cm, a height is 5cm and a distance between a transmitter and a receiver is 20cm. As a result, an output of this system is 1.7112W and an efficiency is 64.050%.
