Different applications now need to evaluate the capacitive behaviors of their devices. Power modules, for instance, are now working at high frequencies and a capacitive behavior appears in addition to the resistive-inductive aspects. Unfortunately these effects may have undesirable effects on the devices and generate additional losses. In order to observe and analyze these effects, the value of the capacitances between each conductor has to be computed. From electrostatic computations with different methods and tools described below, these capacitances can be obtained as capacitances matrices.
Three different matrices exist from electrostatic computation results to direct the capacitance value between two “conductors”. Before beginning any computation, these “conductor” regions have to be defined, corresponding to the elements to be connected with the computed capacitances. The methods are described with InCa3D and Flux…
