基于耦合电感的无线电能传输接收器双频整流器

This article proposes a dual-band wireless power receiver capable of both kHz-band and MHz-band wireless charging. The proposed rectifier automatically switches between two charging modes depending on the frequency band of the input signal. It operates as a class D rectifier at low-frequency band input and a class E rectifier at high-frequency band input. This mode change requires no active elemen...
