A power conversion system including a triple active bridge (TAB) is provided. The system includes a power factor correction (PFC) module and a three port converter (TPC) module, with no post-regulation or additional stages required. The TPC module includes an OBC full-bridge and an APM full-bridge, each being inductively coupled to the output of the PFC full-bridge, thereby forming the TAB. The OBC full-bridge is adapted to convert an AC input into a high-voltage DC output for a high-voltage battery, and the APM full-bridge is adapted to convert an AC input into a low-voltage DC output for a low-voltage battery. The power conversion system can accept a single-phase AC input and a three-phase AC input, has a lower current stress as compared to prior art TPCs, and freely transfers power from among any ports.

Approaches, techniques, and mechanisms are disclosed for packaging electric power components. A power module comprises: a three-dimensional (3D) cooling structure that has a plurality of planar sides; a first set of mountable power components that are mounted on a first planar side in the plurality of planar sides of the 3D cooling structure; a second set of mountable power components that are mounted on a second planar side in the plurality of planar sides of the 3D cooling structure. The second planar side represents an opposing side, of the 3D cooling structure, to the first planar side. The 3D cooling structure includes an interior space containing one or more cooling channels in which cooling fluid is to flow. The interior space of the 3D cooling structure is spatially surrounded by other planar sides in the plurality of planar sides in combination with the first and second planar sides.
