Claim 0:
1. An inductor structure, comprising:
n inductors, wherein each of the n inductors comprises a base plate, a cover plate, a first magnetic column disposed between the base plate and the cover plate, and a coil wound around the first magnetic column, where n≥2; and
m second magnetic column(s), wherein for each of the second magnetic column(s), the second magnetic column is disposed between at least two of the n inductors, the second magnetic column has a first terminal and a second terminal along an extension direction of the second magnetic column, the first terminal is connected to the cover plates of the at least two inductors, and the second terminal is connected to the base plates of the at least two inductors, where m<n; wherein
each of the n inductors and the second magnetic column connected with and disposed on one side of the inductor constitute an inductor unit, and the n inductors and the m second magnetic column(s) constitute a plurality of inductor units;
the n inductors and the m second magnetic column(s) are arranged at intervals along a first direction, and for any second magnetic column, one of the n inductors which is disposed on one side of the second magnetic column in the first direction is denoted as a first inductor, and another of the n inductors which is disposed on the other side of the second magnetic column in the first direction is denoted as a second inductor; and
for any second magnetic column and the first and second inductors on the one side and the other side of the second magnetic column:
air gaps are provided only between the first magnetic column and the cover plate of the first inductor, and between the second magnetic column and the cover plate of the second inductor; or
air gaps are provided only between the first magnetic column and the cover plate of the first inductor, between the second magnetic column and the cover plate of the first inductor, between the first magnetic column and the cover plate of the second inductor, and between the second magnetic column and the cover plate of the second inductor.
