| Summary: | In the power drive system of the Electric Vehicles (EVs)
and Hybrid Electric Vehicles (HEVs), High Voltage (HV) cables play a major
role in evaluating the EMI of the whole system. Transfer impedance (<i>Z</i><sub>T</sub>)
is the most commonly used performance parameter for the HV cable. To analyse
and design HV cables and connectors with better shielding effectiveness
(SE), appropriate measurement and simulation methods are required. In this
paper, Ground Plate Method (GPM) with improvements has been proposed to
measure <i>Z</i><sub>T</sub>. Use of low-frequency ferrites to avoid ground-loop effects
has also been investigated. Additionally, a combination of analytical model
with a circuit model has been implemented to simulate limitations (frequency
response) of the test setup. Also parametrical studies using the analytical
model have been performed to analyse the shielding behaviour of HV cables. |
