一种具有宽范围ZVS和无通信能力的双频双通道无线电能传输系统

Achieving efficient power regulation without communication in wireless power transfer (WPT) systems remains a significant challenge, particularly under varying load and coupling conditions. This article proposes a dual-frequency dual-channel WPT system by introducing a third harmonic resonant channel alongside the fundamental power channel. The third harmonic current serves multiple roles: it enab...
