The trend towards electrification in mobility has led to the increased use of silicon carbide (SiC) semiconductors. These semiconductors are more efficient but also present challenges related electromagnetic interference (EMI) due their higher voltage derivatives. This paper introduces a new high-frequency impedance model for electrical machines. proposed distinguishes itself from existing approaches by being entirely derived Finite Element Method (FEM) simulations, which include...
An impedance model, based on transmission line (TL) theory, is introduced for common mode ferrite chokes. The proposed model takes into account the geometrical properties of choke, distribution electromagnetic fields within core material and impact measurement setup. validity was tested through numerical simulations. As a practical application, applied to estimate complex permeability MnZn NiZn cores from measurements, resulting in range values compatible with those reported other works.
In the present paper a time domain simulation of overall electric drive, comprising power converter, cables and electrical machine is developed in order to analyse detail electromagnetic compatibility system. The simulations are validated by experimental test performed over an industrial converter-motor system, very good agreement obtained between results measurements.
Toroidal ferrites and magnetic cores are a key part of electromagnetic compatibility (EMC). They used in several applications as power converters, low-power supplies, cables, etc. Therefore, it is crucial to properly characterize them for running 3-D simulations. Typically, complex permeability (CMP) taken the main property cores. In this paper effect CMP simulation up 100 MHz investigated. The spectrum has been separated into two regions, split by resonance frequency, simulations models...
Electrical drives consume a great amount of the world’s energy, and this will keep increasing due to electromobility trend. Hence, efficiency electrical must be improved reach sustainability. Silicon Carbide devices have high working frequency lower switching loss, device efficiency. Nevertheless, higher operation frequencies may bring major Electromagnetic Compatibility issues, in addition insulation stress bearing currents. This paper presents simulation process obtain high-frequency model...
This paper presents a full-wave 3-D FEM simulation methodology for magnetic toroidal cores up to 100 MHz. of has gained significant relevance in recent years. However, the use materials some difficulties. Complex permeability is typically only electromagnetic property used cores' simulation. Nonetheless, results suggest that other properties must also be considered high-frequency simulations. The presented particularly practical as it accurately models commercial easily. Electromagnetic...
Common-mode chokes (CMC) are fundamental in electromagnetic interference (EMI) filters. 3-D simulation is becoming more and important recent years as it can take into account some effects that circuit modeling does not consider, such the surrounding environment of CMC. This paper investigates influence complex magnetic permeability on a Mn-Zn CMC its typical application frequency range (below 10 MHz). For this purpose, simple method to extract values by winding cores with copper wire...
This article introduces a comprehensive methodology for analyzing common-mode (CM) ferrite chokes in time-domain (TD) methods, employing lumped dispersive loads, and validates it through typical test setup cable crosstalk assessment. The analysis begins with the experimental characterization of CM choke material properties using coaxial line fixture to obtain its constitutive parameters. Subsequently, simplified convolutional model is obtained, representing impedance when placed on location...
