System Complexity Reduction Approach in the Modelling of a Discrete Power Device

Abstract:
In power application field, the modelling of discrete power devices highlight several issues related to the intrinsic complexity of wide-area silicon structures, featuring several interacting heterogeneous parts. Some complex systems peculiarities can be found in these devices like mutual interaction between sub systems, intrinsic non-linearity, feedback loops and a strong dependency from boundary conditions. The need of modelling such components, with the objective of analyzing and predicting their thermal or electrical internal behavior, represents the key to competitive design. It implies the definition of modelling approaches allowing the whole system complexity reduction, to make it easy analyzable through standard spice-like simulators.
