“…This can be explained by the fact that the switched current is directly proportional to the duty cycles. This analysis is consistent with the work (Zeghoudi, 2021) where the disturbances in CM are mainly due to variations in the voltage in the switching cell and the disturbances in DM are mainly due to variations in currents.…”

“…The advancement of power electronic converters in various electric power sectors imposes new requirements, such as high-frequency switching operations, high power densities, elevated temperatures, and enhanced yields. All specifications must adhere to EMC regulations (Zeghoudi, 2021). The conventional method for EMC prediction involves simulation in the time domain and the use of Fourier transform (Eliana & Koyama, 2014).…”

This paper introduces a detailed approach to model and simulate conducted electromagnetic interference (EMI) in the time domain using Lt-Spice software. The focus of the study is on the Buck converter, with the aim of identifying and characterizing electromagnetic disturbance sources arising from the power supply. The research also seeks to analyze their propagation paths and examine the impact of switch selection and control parameters on the electromagnetic compatibility (EMC) signature of the converter. The proposed methodology employs a comprehensive modeling strategy that accounts for the interactions between various converter components and their associated parasitic elements. By accurately representing the electrical and magnetic fields in the time domain, the simulation captures the dynamic behavior of the system, allowing for a realistic assessment of conducted disturbances. The research begins with a thorough examination of the power supply and its switching behavior. Key device characteristics, including switching frequency, voltage, and current waveforms, are carefully analyzed to understand their influence on conducted EMI. Additionally, the model integrates parasitic elements linked to the power device, such as inductive and capacitive components, to address their impact on electromagnetic emissions. Furthermore, the study delves into the propagation paths of conducted disturbances, considering the parasitic elements of the converter's layout, such as PCB traces, cables, and connectors. It evaluates the effects of these elements on electromagnetic emissions, providing insights into propagation mechanisms and potential coupling paths. Various switch types, such as MOSFET or IGBT, are examined, and their effects on conducted EMI are evaluated. Through comprehensive simulations and analysis, the paper offers valuable insights into the conducted disturbances generated by the DC/DC converter, contributing to a comprehensive understanding of the system's electromagnetic behavior. The findings presented in this study can inform the design and optimization of DC/DC converters, facilitating the development of more EMC-friendly solutions.

“…Current harmonics can negatively affect the operation of the power system and the loads in it [3,4,8,9,11,23]. The distorted current drawn by nonlinear loads causes, among other things, a distortion of the supply voltage, an increase in thermal losses in the conductors, additional load on the neutral conductor, accelerated ageing of the insulation, and the formation of additional dielectric losses.…”

This article deals with problems related to electromagnetic compatibility, which is a very important issue due to the fact of ensuring the proper coexistence of devices and systems in a given electromagnetic environment. The devices manufactured today can, on the one hand, be a source of electromagnetic disturbance emissions and, on the other hand, be susceptible to disturbance signals from the environment. A large group of receivers in which electronic specialised circuits are used are LED lamps. The operation of an RGB LED lamp due to higher harmonic current emissions has been analysed in this paper. Lamp tests were carried out in several stages. In each of them, the values of the generated higher harmonics were analysed and related to the parameters of the current flowing through the lamp. It was shown how the parameters of the current pulse affect the generated harmonics when the value of the luminous flux was changed, its colour was changed, or the built-in function was turned on. It is also shown how, for example, changing the value of an electronic component in the lamp’s power supply changes the parameters of the current and thus the value of the generated higher harmonics.

“…Static converters are made up of electronic switches (diode, IGBT, MOSFET) and passive components (inductance, capacitance), and resistors allowing the conversion and/or the regulation of a voltage (or a current). However, electrical conversion systems are sources of electromagnetic pollution due to the frequency of switching of electronic devices, and the rapid variation of voltage and current as a function of time [1][2][3]. So the main sources of electromagnetic interference (EMI) in power electronics come from switching converters switches and produce essentially conducted and radiated emissions [4][5][6].…”

Introduction. Rectifiers are the most important converters in a very wide field: the transport of electrical energy in direct current and in the applications of direct current motors. In most electrical and electronic systems, rectifiers are non-linear loads made up of diodes, therefore they are a source of harmonic pollution at a base frequency with a distorting line current signal that generates electromagnetic interference. There are two disturbance modes: common mode and differential mode. These disturbances caused by the rapid variation of current and voltage as a function of time due to the switching of active components, passive components such as inductors, capacitors, coupling, etc. The purpose of this work is to study the conducted emissions generated by a rectifier connected to the Line Impedance Stabilizing Network in an electric circuit. The determination of these disturbances is done for firstly both common and differential modes at high frequency, and secondly harmonics current, line current at low frequency. The novelty of the proposed work consists in presenting a study of disturbance generated by rectifiers using simulation and also experimental measurements at low and high frequencies in order to compare the results. Methods. For the study of the disturbances conducted by the diode bridge converter (rectifier), the sources of conducted electromagnetic disturbances were presented in the first time. Then, the common and differential modes were defined. This converter was studied by LTspice Software for simulation and also experimental measurements at low frequency for harmonics current and high frequencies for disturbances in common and differential modes. Results. All the simulations were performed using the LTspice software and the results obtained are validated by experimental measurements performed in the APELEC laboratory at the University of Sidi Bel-Abbes in Algeria. The obtained results of conducted emissions at high frequency and total harmonics distortion of current at low frequency are compared between simulation and experiment.
