1. A transformer, comprising:
a magnetic core set, comprising:
a first magnetic core;
a second magnetic core, parallel to the first magnetic core; and
a magnetic column pair, comprising a first magnetic column and a second magnetic column, the first magnetic column being substantially parallel to the second magnetic column, wherein the first magnetic column and the second magnetic column are between the first magnetic core and the second magnetic core, and a number of the magnetic columns is two; and 2N winding pairs, wherein N is a positive integer greater than or equal to 2, each of the winding pairs comprises a high-voltage side winding and a low-voltage side winding, each of the winding pairs surrounds one of the first magnetic column and the second magnetic column, and a first winding direction in which the high-voltage side windings surround the first magnetic column is substantially opposite to a second winding direction in which the high-voltage side windings surround the second magnetic column, and
outer sides of the first magnetic core and the second magnetic core are aligned with or protrude from outer sides of the 2N winging pairs.
