“…This means that the output current and voltage will be distorted, affecting the vehicle's resistance and leading to overload. To address these issues, the insulation of the equipment may be improved, with nanocomposites widely used for the reduction of interference [216,217], while electromagnetic interference may be somewhat reduced by the use of upgraded passive or active LC [219], radio frequency (RF) or three-line filters [214], IGBTs and capacitors [219], GaN transistors [220],…”

Over the years, an increase in the traffic of electric and hybrid electric vehicles and vehicles with hydrogen cells is being observed, while at the same time, self-driving cars are appearing as a modern trend in transportation. As the years pass, their equipment will evolve. So, considering the progress in vehicle equipment over the years, additional technological innovations and applications should be proposed in the near future. Having that in mind, an analytical review of the progress of equipment in electromobility and autonomous driving is performed in this paper. The outcomes of this review comprise hints for additional complementary technological innovations, applications, and operating constraints along with proposals for materials, suggestions and tips for the future. The aforementioned hints and tips aim to help in securing proper operation of each vehicle part and charging equipment in the future, and make driving safer in the future. Finally, this review paper concludes with a discussion and bibliographic references.

“…Such high-frequency converters are characterised by high switching frequency and compact layout, which generates a great level of interference. The management of EMI has been recognised as one of the major challenges that limit the widespread application of high-frequency power converters by many researchers [1][2][3][4][5][6][7][8][9]. Therefore, there is an urgent need to solve the EMI problems in high-frequency converters.…”

“…Hence, it is difficult for the high-frequency converter to pass the conductive EMI standard [6,7]. In addition, WBG devices with faster FIGURE 1 Categorisation of main research topics on EMI reduction for high-frequency power converters switching speeds and greater dv∕dt and di∕dt are widely used in high-frequency converters, which generate significant EMI at high frequency [2, 6-9, 12, 13]. In conclusion, noise sources in high-frequency converters produce more interference than conventional converters.…”

High‐frequency power converters with high switching frequency and compact layout are characterised by high power density and high efficiency, which is superior to conventional converters in many aspects. However, the management of electromagnetic interference (EMI) is a significant limitation for their widespread application. Recent conductive EMI suppression methods are reviewed in this paper. The mechanisms and characteristics of the reviewed methods are discussed in detail. Then, the EMI attenuation of the mentioned methods is compared from the perspective of attenuation band, attenuation amplitude, and cost respectively. It is demonstrated that both the source and the propagation path have a significant impact on EMI problems in performance of high‐frequency power converters. Several suggestions can be proposed based on the reviewed researches. Firstly, both the potential matching method and the balance winding method in transformer design can achieve a significant EMI reduction at all frequencies within the frequency range of conducted EMI. Secondly, spread‐spectrum modulation techniques are suggested to be applied in MHz converters instead of constant frequency control. Thirdly, the reviewed gate driver optimisation methods have a remarkable EMI suppression effect at high frequencies and still work for the suppression of radiated EMI. Finally, filters can have a reduced volume if the reviewed methods are applied.
