Vers une methodologie de conception des interconnexions pour les dispositifs de l'electronique de puissance

Abstract : Harmful cabling effects are well known by designers of power electronics converters. They try to decrease over voltages, losses and EMC interactions. However, interconnection design is still complex because of electromagnetic phenomena, which are not easy to predict during the design step. Classical methods and techniques based on the designer experience are not suitable to develop complex structures as ones used in industrial applications.
Firstly, a generic cabling model based on input/output terminals has been proposed. Automatic links between InCa (Inductance Computation) and circuit simulators (Saber, P-Spice) has been developed. The automated generation of "cabling" model represents a significant improvement in accurate modeling of power converters and can be included in virtual prototyping approach. This allows analyzing signals which can not be accessible with traditional measurement methods. Then, once cabling effects have been identified with the previous tools, an original approach focussed on parasitic cabling elements allows reducing disturbances and imbalance current involved by the cabling. Cabling rules are proposed from impedance matrix (matrix representation of the generic model) in order to judge the quality of the cabling and can be used as objective function in optimization process. This work represents a major improvement in cabling design.
