High voltage automotive EMC component measurements using an artificial network

Abstract

This paper investigates the adaptation of the standard 12V automotive conducted emissions component EMC measurement method, as defined in CISPR 25, to the ever increasing high voltage automotive components seen in hybrid electric, fuel cell, and the alike vehicles. Due to significantly higher voltages and currents and variations in shielding strategies, conventional automotive measurement methods do not always produce vehicle representative results. Experimental and simulation results are presented which show that artificial networks, as defined in CISPR 25, should not be used for validation of high voltage automotive components in either conducted voltage or current measurements.
