  4. 3. Power cables in battery electric vehicles used in underground mining : Analysis of electromagnetic dynamics in high-power cables and development of application-specific design strategies for reduction of EMI

    University essay from Uppsala universitet/Elektricitetslära

    Author : Chisom Miriam Ekweoba; [2019]
    Keywords : ;

    Abstract : The electrification of the automotive industry is growing in popularity, considering the environmental impacts of the conventional diesel-powered automobile. However, from the electromagnetic compatibility (EMC) viewpoint, it is observed that the use of variable-frequency drives (VFD) and relatively high-power cables to propel electrical motors has led to a considerable rise in electromagnetic interference (EMI) within and outside the machine.
