摘要

This article proposes an intermediate coil-aided wireless charging systems via interactive power transmitting mechanism. The study is motivated because the occurrence of coil misalignment is known to affect the transfer efficiency and may destabilize the output voltage. The article is, hence, devoted to designing auxiliary repeater-aided coil module along with interoperable power adjustment, anticipating enhancing the tolerating capability of misalignment during the wireless charging. The design of this system includes two half-bridge inverters deployed to drive main transmitting coil and repeater coil. Circuit operations consist of repeater-aided mode and power-interactive mode. An interoperable power-transmitting strategy is applied to regulate the gain following the movement of receiving coils, by which a higher efficiency is ensured while a constant voltage is better maintained. To confirm the effectiveness of this design approach, both circuit simulation and hardware realization are accomplished under different test scenarios. Experimental outcome support the practicality of the approach, serving as beneficial references for wireless charging applications.
