摘要（英）：

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 comprises a first current equalization circuit associated with a DD coil and a second current equalization circuit associated with a Q coil, wherein the first current equalization circuit and the second current equalization circuit control the respective output current values thereof to maintain the deviation of two groups of output currents within a set range. The present invention solves the problem that an output current of a DDQ magnetic structure is uneven, and can improve the charging efficiency and the charging power; and on the basis of wireless charging of an automobile, the power transmission magnitude and efficiency in the presence of a positional offset can be improved.
