Design and Optimisation of Integrated Receiving Module for Segmented Guide Rail Dynamic Wireless Power Supply System

ABSTRACT

Dynamic wireless power transfer technology has significant advantages in the power supply of mobile loads, achieving electrical isolation between the load and the charging line, and meeting the continuous work demand of the mobile load. The segmented guide dynamic wireless power transfer is the most widely used at present, but the uneven distribution of the magnetic field at the transmitting end of the system leads to power fluctuation during the whole operation cycle, which limits the further development of this technology. Based on this, the distribution characteristics of the dynamic coupling magnetic field of the segmented guide rail are analysed, and an integrated receiving module with a compensation structure is proposed. By compensating the transverse magnetic field component coupled by the receiving coil, the lack of coupling performance of the planar receiving coil in the transition state is made up, and the problem of low receiving power in the transition state is solved. Finally, the experimental platform of the segmented guide rail dynamic wireless power supply system is set up, and the effectiveness of the proposed scheme is verified by comparing the total power received by only planar receiving coil and adding compensation receiving coil.
