摘要

本文报道了一种用于电动滑板车的无线感应充电方案的设计、构建和集成，工作频率为6.78MHz，输出功率为110 W。该系统在发射端采用推挽式EF级逆变器，在接收端采用铁氧体屏蔽和倍压型全波D类整流器，实现了69%-75%的DC-DC IPT效率，并在全充电功率下具有良好的容错能力。

A 110W E-scooter Wireless Charger Operating at 6.78MHz with Ferrite Shielding

This paper reports on the design, construction and integration of a wireless inductive charging solution for an electric scooter, operating at a frequency of 6.78MHz and providing an output power of 110 W. With the use of a push-pull Class EF inverter at the transmit end, as well as ferrite shielding and a voltage-doubler full-wave Class D rectifier at the receive end, this system achieved a DC-DC IPT efficiency of 69%–75% and exhibited good tolerance to misalignment at full charging power.
