Dynamic Wireless Power Transfer in Urban Area- EMI on Traffic Signal Cables

This 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
