“…Because of the locality properties of the reluctance matrix, it can safely sparsified by a truncation process, while still keeping the solution valid and accurate [9]. Later, by applying the sparsified reluctance matrix to both sides of (3), the new formulation which is shown in (4), will be achieved.…”

This paper presents a method to deal with the illposed and rank-deficient linear systems arising from accelerated partial element equivalent circuit-based electromagnetic simulations via a reluctance method. Since conventional, direct methods, cannot be used to solve these kind of problems, regularization techniques need to be employed. Among various regularization techniques, a least square-based method entitled LSQR is utilized to solve the rank-deficient problems. The proposed method is specially proper for the models where capacitive couplings can be neglected, since magnetic field is the dominating factor, like problems within power electronics area. The correctness of the presented PEEC-based solver is ensured by studying bus bar models which are a part of a frequency converters with the application in power electronics.

“…When dielectric media is considered and all parameters of the PEEC model for all directions of the coordinate system are determined its volumetric discretisation for each direction of the cartesian coordinate system is needed when an orthogonal 'Manhattan Discretisation' is used [9]. According to the aforementioned parallel plate capacitor arrangement the dielectric volume between the plates with length l = 10mm, width b = 10mm and height h = 630μm is considered.…”

Considerations refer to thermal optimisation and its coherence with the appearance of electrical parasitics in power electronic systems. Analytical and finite element simulation assisted analysis of thermal resistance depending on geometry of layered assemblies is discussed. Resulting approach provides a basis for considerations on parasitics applying partial element equivalent circuit method (PEEC).
