A New Methodology for Extraction of Dynamic Compact Thermal Models
  An innovative and accurate dynamic Compact Thermal Model extraction method is proposed for multi-chip power electronics systems. It accounts for thermal coupling between multiple heat sources. Transient electro-thermal coupling can easily be taken into account by system designers. The method is based on a definition of the Optimal Thermal Coupling Point, which is proven to be valid even for transient modelling. Compared to the existing methods, the number of needed 3D thermal simulations or measurements is significantly reduced.
