A.R. Ruddle, L. Low. Simulation of Basic Restrictions for a Seated Human Model Exposed to Magnetic fields due to traction current transients in Hybrid and Electric Vehicles. 13th European EMC Symposium, September 1st-4th, Gothenburg, Sweden.


Numerical simulations based on an anatomically detailed human model exposed to low frequency magnetic fields that are representative of traction current paths in vehicles with electrical powertrains have been used to estimate the exposure of vehicle occupants. The results obtained based on a measured traction current waveform from a small electric vehicle indicate that induced current density and internal electric fields would comply with the basic restrictions at frequencies below 3 kHz. However, the estimated exposure relative to the basic restrictions of ICNIRP 2010 is found to be slightly higher than the estimated exposure relative to the corresponding field reference levels in one test case. This suggests that the ICNIRP 2010 magnetic field reference levels may not provide reliable protection in terms of the associated basic restrictions on internal electric field.
