3D packaging technology incorporated power conversion module for automotive distributed energy resource application

Abstract

A three-dimensional (3D) packaged electronic module is proposed in this paper that serves as power conversion module for emerging automotive distributed energy resource (DR) applications. Thermal dissipation and parasitic inductance are identified as two major issues causing energy loss during transmission. Literature and industrial approaches to mitigate these issues are reviewed, which features a DC-DC inverter in hybrid electric vehicle (HEV) or plug-in hybrid electric vehicle (PHEV) as an example. A 3D package technology is therefore developed and CAD simulation tool is then employed to investigated and evaluated its effectiveness in electricity conversion. The result shows the package halves inductive parasitic with significant improvement on thermal efficiency. The implementation of this technology in automotive power converter is expected to achieve high efficient and reliable power conversion.
