In this paper, a comparative study is carried out between the carrier (SPWM), third harmonic injection (THIPWM), and space vector (SVPWM) modulation schemes in terms of conducted (common and differential modes) and radiated electromagnetic interference (EMI) generated by three-phase two-level voltage source inverters. For this purpose, an experimental setup of the converter feeding an induction machine is developed with the aim to measure the conducted emission propagated back into the dc source and the radiated field in the vicinity of the power conversion device. Experimental results are given and analyzed in time and frequency domains. The comparative study between the three modulation methods carried out in the frequency domain shows that the SVPWM method has better EMI performance. Moreover, a high frequency model of the converter feeding the induction machine is simulated using SPICE-based simulation software. Good agreement is found between the experimental and simulation results in terms of conducted interferences.

Shielding Effectiveness of Perforated Screens Through an Inverse Problem-Based Resolution

This paper shows that the radiated fields from perforated plane shields excited by a circular loop are the same than those produced by one or several magnetic dipoles located on the plane of the apertures. The way to derive this equivalent model is based on an inverse problem using optimization methods and near-field calculation (method of moments) or measurements. The proposed approach allows to evaluate the shielding effectiveness of the perforated screens. All results are compared with experimental values to check the validation. Such equivalent models could be used to avoid meshing screens in case a 3-D problem involving an enclosure with arrays of apertures or to simplify EMC analysis of power electronic devices having shielded enclosures.

“…In [3], authors applied the Artificial Network and the Pseudo Zernike Moment Invariant and presented a parametric study to evaluate the influence of the different parameters such as measurement resolution and height. This methodology was improved, in [4], by use of GA in the FD in order to accelerate the convergence of the algorithm. To enhance the computational time, Benyoubi et al [5], proposed a fast technique based on the matrix inversion and an optimization procedure, which allows finding equivalent sources with a smaller number of dipoles, compared to [6].…”

This paper deals with magnetic source characterization in time domain. The basic idea is to solve the inverse problem using the measured near field radiation cartography. In order to ensure the identification procedure, the Time Reversal (TR) technique is used. This procedure allows both the spatial and temporal focusing determination by forcing waves to virtually converge to their initial source. The originality of the proposed methodology is to present a full time domain study of a magnetic source reconstruction. Indeed, this approach is particularly suitable for structures that emit non-sinusoidal radiations such as power electronic systems. First, the Electromagnetic Time Reversal (EMTR) basis are introduced. Then a simulation case study is discussed. Finally, results from an experiment test are presented to verify the proposed methodology. The measured results are in good agreement with the calculated electromagnetic fields. The experimental validation shows that compared to other identification techniques, especially those developed in the frequency domain, the proposed approach is more efficient and simple.
