| Abstract |
Due to the nature of electronic power processing, the design of power electronics components, converters and systems has always involved many disciplines: from circuits and solid-state physics, to electromagnetics, systems and control, thermodynamics, structural mechanics, material science and reliability. An approach to the integration of the multidisciplinary analysis and design in power electronics is described. Its main goal is to enable effective analysis of the multidisciplinary interactions at higher levels of accuracy than can be achieved with the simplified algebraic models customarily used today. The major components of the approach are integration of the well-known modeling and analysis techniques that already exist in different disciplines, and the development of systematic techniques for model reduction and automated parameter extraction based on the spatial, temporal and functional distribution of the physical phenomena. The core methodology for achieving this goal is the efficient integration of the computer aided design software tools that are commercially available and proven in different disciplines, based on the use and further development of the existing open standards for software integration. The feasibility of the approach is illustrated through two examples of integrated analysis used for parametric study of the tradeoff between the electromagnetic interference and thermal performance of a simple integrated power electronics module. |
