AI Technical Summary

Technical Problem

In existing wireless charging technologies, the receiving coil assembly is prone to unexpected coupling interference when integrated with a parallel resonant inductor, and robot pose deviation leads to low charging efficiency.

Method used

A double-sided multiplexing structure of the magnetic core is adopted, in which the resonant coil layer and the receiving coil layer are respectively placed on both sides of the magnetic core. The magnetic core layer is used as a shielding layer to reduce unintended coupling, and the capacitance value of the parallel resonant branch is adjusted in real time through an adaptive tuning method to maintain efficient charging.

Benefits of technology

It effectively eliminates unintended coupling interference, improves the efficiency and robustness of the wireless charging system under pose shift, and is particularly suitable for wireless charging of mobile robots.

Abstract

The application relates to the technical field of wireless charging and discloses a wireless charging system based on double-face multiplexing of a magnetic core and a self-adaptive tuning method. On the one hand, the application discloses the wireless charging system based on double-face multiplexing of a magnetic core. The wireless charging system comprises a transmitting end and a receiving end. The receiving end comprises a receiving coil assembly and a receiving controller. The receiving coil assembly comprises a resonant coil layer, a first magnetic core layer, a receiving coil layer and an insulating protective layer which are sequentially arranged. The receiving coil layer and the resonant coil layer are arranged on the two sides of the first magnetic core layer respectively. The resonant coil layer is arranged in the direction away from the transmitting end. The receiving controller is electrically connected with the resonant coil layer and the receiving coil layer respectively. The application adopts double-face multiplexing of a magnetic circuit. The magnetic shielding anti-interference magnetic integrated structure and the closed-loop tuning algorithm are deeply cooperated. The coupling crosstalk problem caused by the same-side integration is effectively solved.
