中文摘要

本文提出了一种用于电动汽车的高功率、高频无线电能传输系统，具有轻量化和紧凑的线圈设计。通过采用多层非均匀自谐振线圈，无需外部补偿电容，并利用多层铜层间的电流分担效应降低了高频传导损耗。

English Abstract

A high-power, high-frequency wireless power transfer system for electric vehicles (EVs) is proposed in this article with lightweight and compact coil design. Leveraging a multilayer nonuniform self-resonant coil, no external capacitor is needed for compensation and the high-frequency conduction loss is mitigated by sharing current between multiple copper layers. The analytical model for the propos...
