CURRENT EQUALIZATION CIRCUIT AND METHOD BASED ON DDQ MAGNETIC STRUCTURE

摘要

The present invention relates to the technical field of wireless charging, and in particular to a current equalization circuit and method based on a DDQ magnetic structure. The current equalization circuit includes a first current equalization circuit associated with a DD coil and a second current equalization circuit associated with a Q coil; and the first current equalization circuit and the second current equalization circuit maintain the deviation of two groups of output current within a set range by controlling respective output current values. The present invention solves the problem of uneven output current of the DDQ magnetic structure, and can improve the charging efficiency and the charging power; and on the basis of the wireless charging of a vehicle, the present invention can improve the power transmission magnitude and efficiency in the presence of position deviation.
