On the reliability of distributed power systems: a macro- to microlevel overview using a parallel DC-DC converter

Using a parallel DC-DC power converter as an example, the authors outline the reliability issues of a distributed power system (DPS) at system, module, component, materials and fundamental (atomic) levels. The comprehensive approach proposed in this paper is an alternative to the traditional statistical/probabilistic approach to reliability analysis and fulfill the following goals. It will enable in-depth understanding of the failure mechanisms and reliability issues of a DPS at macro and micro levels, develop robust power-electronic systems and components, and help develop reliable testing methodologies and design techniques.
