EnglishThis study deals with a preliminary analysis of the electromagnetic interference (EMI) produced by a dynamic wireless power transfer (DWPT) system on an underground traffic signal cable. The considered DWPT is composed by an electrified lane with short-track pads architecture. The induced effects in a multiconductor underground cable are calculated by the theory of field-excited multiconductor transmission line (MTL) where the distributed sources are derived from the electromagnetic field generated by the DWPT coils operating at 85 kHz and transferring a power of 10 kW. The obtained preliminary results, validated by comparison with other methods, show that the induced current on a traffic signal cable is small for higher odd harmonics, while it is negligible for even harmonics. Thus, only the first harmonic could produce EMI.
