中文摘要

高频无线电能传输(HF-IPT)系统具有高容错性,但大磁场体积易导致异物耦合,引发系统失谐及发热。本文提出一种基于EF类逆变器开关谐波的感应电压估计方法,用于监测环境条件及异物影响,提升系统运行的安全性与可靠性。

English Abstract

One of the advantages of high-frequency inductive power transfer systems is the high tolerance to misalignment and large air-gaps. However, the inherently large magnetic field volumes can lead to coupling of additional foreign objects with the primary, causing possible detuning of the system and heating of the objects. These foreign objects and the conditions of the local environment can load the ...
