Abstract

The invention provides a distributed receiving coil structure applied to a three-phase dynamic wireless power supply system. A receiving coil is mounted at the bottom of charging equipment; the receiving coil is a rectangular coil, the length of the rectangular coil is 1coil, the width of the rectangular coil is wcoil, the number of turns of the rectangular coil is NS, and the distance between two adjacent turns of coils is d; according to the distributed receiving coil structure, the distance between turns of the receiving coil is reasonably designed, so that the induced voltage generated by a harmonic traveling wave magnetic field generated by a transmitting end in the receiving coil can be eliminated, and the fluctuation of the output voltage in a three-phase dynamic wireless power supply system is effectively inhibited; and decoupling of the output voltage and the position of the receiving end is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a distributed receiving coil structure applied to a three-phase dynamic wireless power supply system. Background technique [0002] Compared with the traditional wired power supply method, wireless power supply technology has the advantages of non-contact, good electrical safety, high reliability in harsh environments, and automatic charging. It is currently widely used in electric vehicles, underground equipment, rail transit and other fields. In order to realize fast charging of the on-board battery, it is usually necessary to make the on-board battery work in a constant voltage / constant current charging mode. For a dynamic wireless power supply system, the receiving end will move with the device during the charging process, resulting in changes in the mutual inductance between the transmitting coil and the receiving coil, resulting in fluctuatio...
