摘要

随着电动汽车的快速发展,无线电力传输技术(WPT)成为全球的热点技术之一。目前,电动汽车充电的感应功率传输(IPT)面临着铁氧体铁心棒饱和磁通过低所带来的效率问题。纳米晶带状磁芯具有高饱和磁通和低功耗的特点,是一种理想的选择。本文将对纳米晶增强磁芯和铁氧体TDK PC40磁芯的双d片式耦合器进行详细的磁场磁通密度、车体周围空气漏磁、功率损耗分布、磁屏蔽等方面的分析和比较。

A Comparison of Advanced IPT Systems with Nanocrystalline and Ferrite Cores for Wireless EV Charging
Wireless power transfer (WPT) is one of the global highlight techniques with the rapid development of electric vehicles (EV). Currently, inductive power transfer (IPT) for EV charging faces the efficiency problem caused by the low saturation flux in the ferrite core bars. The nanocrystalline ribbon core is an advisable choice for the features of a high saturation flux and low power loss. In this paper, a double-D pads coupler with nanocrystalline core enhanced and ferrite TDK PC40 core will be detailed analyzed and compared regarding the magnetic field flux density, the air flux leakage around the vehicle body, the power loss distribution, and the magnetic shielding for wireless EV charging.
