Abstract: A modular power device is used for mounting on a main plate. The modular power device includes a first substrate, a driving module and a converting module. The first substrate having a first axial direction and a second axial direction substantially perpendicular to the first axial direction is inserted into the main plate, such that the second axial direction is substantially perpendicular to the main plate. The driving module is located on one side of the first substrate and electrically connected thereon. The converting module is located on the other side of the first substrate and electrically connected to the driving module. A length of the converting module is substantially equal to that of the first substrate in the first axial direction, and a width of the converting module is smaller than a length of the first substrate in the first axial direction.

Abstract: The present invention provides a transformer having assembled bobbins and a voltage transformation module having the transformer. The transformer includes a base, bobbins, secondary windings and two magnetic cores. The base is provided with a penetration hole. The bobbins are disposed in the base and each has an annular groove, a hollow portion corresponding to the penetration hole, and protrusions formed on a surface of the bobbin. The protrusions form a gap between the two adjacent bobbins when the two adjacent bobbins are assembled with each other. The secondary windings are disposed between the bobbins and each has a through-hole corresponding to the hollow portion. The two magnetic cores penetrate the penetration hole of the base, the hollow portions of the bobbins, and the through-holes of the secondary windings to assemble them together.
