This paper presents to find a sufficient model of integrated passive structures for high frequency analysis and prediction in power electronic circuits. At high frequencies there are many parasitic oscillations that begin to circulate in the power circuits. Some sources of these oscillations include inter-component connections and their environment begin having electromagnetic significance, unmodeled characteristics in the semiconductor devices, Parasitic impedance characteristics of discrete passive components, Interference from an imperfect source and a ground plane and Interference from radiation. A simulation model involving most of these factors can prove valuable in distinguishing between the causes of parasitic oscillations. A designer can modify the parameters of a particular parasitic element, and observe its effect on the oscillations, hence seeing which factors are the most significant.

“…Some recent studies [71] [72] have involved in finding the way to increase the magnetic energy in a core window adding a magnetic layer such as C350 [73] ferrite polymer composite (FPC) for example. Models were developed and results seems pomising since they could improve significantly the leakage inductance but they must also maintain the efficiency.…”

The More Electric Aircraft (MEA) has motivated aircraft manufacturers since few decades. Indeed, their investigations lead to the increase of electric power in airplanes. The challenge is to decrease the weight of embedded systems and therefore the fuel consumption. This is possible thanks to new efficient power electronic converters made of new components. As magnetic components represent a great proportion of their weight, planar components are an interesting solution to increase the power density of some switching mode power supplies. This paper presents the benefits and drawbacks of high frequency planar transformers in DC/DC converter, different models developed for their design and different issues in MEA context related to planar's specific geometry and technology.

“…Furthermore, the high memory requirements and the long computation times do not facilitate optimisation. For these reasons, engineers often use analytical formula (see, e.g., [4], [7], [8]) for the design and optimisation of such components, since they allow short computation times and low memory requirements. However, solving Maxwell's equations with analytical approaches necessitates approximations, which are not always valid.…”

“…However, solving Maxwell's equations with analytical approaches necessitates approximations, which are not always valid. For instance, in [7] and [8], magnetic and dielectric problems are solved separately, thus significantly simplifying the study but, at the same time, approximating the actual behaviour of the real working component. For many cases this approach offers a valid and useful approximation which, however, is not valid in general [9].…”

A fast and general Partial Element Equivalent Circuit (PEEC) method based on the Fast-Fourier-Transform (FFT) is proposed for the first time. The numerical tool only requires common CAD data input files (e.g. .stl format), then the discretization process is performed automatically by means of a fast voxelization technique based on ray intersection, thus drastically reducing the human effort required to setup the model. The method allows for considering at the same time inductive and capacitive effects, and is focused on power electronics applications where propagation effects can be neglected, whereas all the other electromagnetic phenomena are considered. Specifically, the proposed method is particularly suited for problems where both electric and magnetic fields are equally important and therefore quasistatic approximations do not apply. An ad-hoc preconditioner which significantly speeds-up the solver is also proposed and, thanks to the FFT, both memory and computation time are significantly reduced, without the need of applying data compression. Both linear and non-linear materials are considered by the proposed FFT-PEEC method. Sample implementation of the method is made publicly available.
