Modular power device

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 has a first axial direction and a second axial direction perpendicular to the first axial direction. The driving module is located on one side of the first substrate, the converting module is located on the other side of the first substrate, and includes a second substrate parallel to the main plate, wherein two opposite sides of the first substrate are inserted into the main plate and the second substrate. A length of the converting module is 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.

What is claimed is:
