Vers un Outil de Conception de Câblage : Le Logiciel InCa

Abstract : The augmentation of technological level of power static converters due to increasing frequency performances of semi-conductors and due to the need of redueing the sizes of the structures makes their design more and more tricky. The use of up-to-date components with high power of commutation does not allow to negleet the electrical characteristies of connections not only face to inadmissible overvoltages when semiconductors turn on but also when for their a.~sociation in parallel in high power structures. The characterization of cabling impedances before the realization of the prototype remains the privileged way in the design of structures which allows to reduce costs and delays. For this, the simulation is necessary to model connections. InCa. simulation 1001 dedicated 10 the characterization of cabling inductances using PEEC method' has been developped to ensure this stage of design. A method for modelling has been established. It consists in looking for the equivalent electrical circuit of connections considering not only the skin and proximity em~Cb but al~o the presence of a ground plane. The automatÎc coupling of InCa with an clectrical simulation tool such as SPICE atlows to use the results given by InCa in order to obtain the cuurent and voltage wave fonn.~ of the converter. InCa whose database is adapted to the solving method has a110wed to characterize varioul\ cabling technologies from integrclted circuit. hybrid technology to bus bar technology more and more used in the power electronics structures.
