1. A method of modular assembly comprising:
- assembling same first and second power-module assemblies that each include a stack of power stages and a manifold;
attaching a first endcap, having manifold cavities and inlet and outlet ports, to the first power-module assembly; and
attaching a second endcap, having manifold cavities and inlet and outlet ports, to the second power-module assembly, wherein the inlet and outlet ports have different placements on the first and second endcaps.

Abstract
According to one embodiment, a power-module assembly includes a power-module stack having coolant chambers interleaved with power modules and supply and return manifold channels extending axially along the stack. An endcap has a major side defining recessed inlet and outlet manifold cavities aligned with the channels and inlet and outlet ports disposed on one or more minor sides that are perpendicular to the major side.

15. A method of modular assembly comprising:
-
assembling same first and second power-module assemblies that each include a plurality of power modules arranged in a stack, each power module including a frame having a first opening with a power stage disposed therein and a second opening, wherein, for each of the first and second power-module assemblies, the power modules are arranged in the stack such that the second openings are aligned to define manifold channels extending axially along the stack and such that the power stages are spaced apart to define coolant chambers interleaved with the power stages and in fluid communication with the manifold channels; attaching a first endcap, having manifold cavities and inlet and outlet ports, to the first power-module assembly; and attaching a second endcap, having manifold cavities and inlet and outlet ports, to the second power-module assembly, wherein the inlet and outlet ports have different placements on the first and second endcaps. - View Dependent Claims (16, 17, 18, 19, 20)
