Evaluation of Radiated EMI in 42- V Vehicle Electrical Systems by FDTD Simulation

In this paper the authors discuss the improvement of flexible load management in moving from 12-V electrical systems in vehicles to 42-V in terms of electromagnetic compatibility (EMC) and reducing electromagnetic interference (EMI). This is also part of the so-called More Electric Vehicle (MEV) conceptual scheme, which adds further loading to a vehicle's electrical components. A finite-difference time-domain (FDTD) method is employed to provide a 3-D numerical scheme to predict EMI. The method applied is suitable for determining EMI for both dc/dc converters as well as dual-voltage vehicle electric plants. The 3-D method allows for accurate yet geometrically complex structures, improving researcher's confidence in its predictive power. The method also allows for the tracing of EM emissions.
