“…A zoom in on the corresponding to the switching time interval shows a periodic and oscillatory phenomenon is visible This phenomenon is due to brutal switching of switches and to the effects of connecting inductors and passive components of converters [14][15][16][17][18][19][20].…”

This work aims to investigate the electromagnetic disturbances generated by a rectifierchopper association. Electromagnetic conducted emissions are a phenomenon that is difficult to predict, particularly within a complex power grid which includes static converters, considered to be the origin of these disturbances. In this paper, the EMC behavior of a switching cell is studied, using both experiments and simulations. A comparison results is also presented. Shape and amplitude of disturbances carried out will play an important role in the propagation phenomena of disturbances over a network using a Line Impedance Stabilizer Network (LISN), simulations have been done with Ltspice software. The results underscore that the nature of disturbances induced in the network is dependent on the operating region of the bridge. The main conclusion of this work is that this device is really electromagnetic pollutant and must then be taken into account, as a whole, in any study implying this kind of converters. The results will be used in optimizing the dimensions of EMC filters to be placed at the input side of the converter depending on the network and converter's impedances.

The commutation of semiconductors and their interactions with parasitic elements linked to the environment is known to be the main source of interferences conducted in power electronic converters. Thus, identifying these sources of interferences in commutation cells and determining the level of these conducted emissions generated in energy conversion systems presents a major challenge for designers. In this work, a study of the electromagnetic interferences (EMI) generated by the association of serial rectifier-chopper connected to a Line Impedance Stabilization Network (LISN) is proposed, in which a determination of these interferences is presented in both common and differential modes. All simulations are carried out using the LT-spice software and the results obtained are validated by experimental measurements realized at APELEC laboratory (University of Sidi Bel-Abbes, Algeria).

“…The boost converter, integral to EV applications for elevating battery voltage, assumes a central role in this landscape [1], [2]. Despite their ubiquity across diverse industries, these converters generate pollution owing to rapid switching characterized by quasi-trapezoidal waveforms [3]. The primary objective of our research is to mitigate conducted electromagnetic stresses in a boost converter tailored for EV applications [4], [5].…”

This article delves into the growing demand for efficient power conversion technologies accompanying the rise in electric vehicle (EV) adoption. Boost converters, essential for increasing the battery pack voltage to propel EV motors, pose a challenge due to the electromagnetic interference (EMI) generated by the high switching frequency of power devices. To address this issue, practitioners employ zero-voltage switching (ZVS) and zero-current switching (ZCS) techniques. In this comparative study, we systematically evaluate the effectiveness of these soft switching techniques in reducing conducted EMI in boost converters designed for EV applications. The results illuminate the potential of both ZVS and ZCS in significantly mitigating EMI emissions when compared to conventional hard-switching methods. Notably, ZVS soft switching emerges as more efficient and effective, particularly under higher loads, while ZCS soft switching excels in reducing EMI at lighter loads. In conclusion, the study asserts that ZVS soft switching presents a more promising solution for curtailing conducted EMI in boost converters for EV applications, particularly in high-load scenarios. However, it underscores the importance of considering specific operational conditions when deciding between the two techniques.
