1. A power conversion module, comprising:
a circuit board including at least one conductive pattern disposed thereon; and
a transformer, disposed on the circuit board, the transformer including:
a primary winding, including at least one coil section;
a plurality of secondary windings, including a plurality of conductive plates, each of the conductive plates including:
two pins, extending along a first direction, wherein the transformer is physically connected to the circuit board through the two pins for electrically connecting to the circuit board;
a single-layered main body, having an opening; and
two intermediate segments, extending along a second direction between the single-layered main body and the two pins, wherein the single-layered main body is coupled to the two pins via the two intermediate segments, and the two intermediate segments are located at both sides of the opening, and the second direction is perpendicular to the first direction; and,
a magnetic core assembly, including a middle post, wherein the coil section and the single-layered main bodies of the conductive plates are arranged in a staggered configuration, the middle post passes through a center of the coil section and the single-layered main bodies of the conductive plates,
wherein the secondary windings are divided into a first group and a second group, and the conductive plates of the first group are connected in series and the conductive plates of the second group are connected in series,
wherein the pins of the conductive plates of the first group and the pins of the conductive plates of the second group are respectively arranged on two opposite sides of the middle post,
wherein in the second direction, a distance from the pins of the conductive plates of the first group to the pins of the conductive plates of the second group is greater than a distance from the pins of the conductive plates of the first group to the middle post.
