Riassunto analitico
In the last 5 years several automotive company, announced combustion-only engines switch-off production in favor of electrical engines for full-electric or hybrid solutions. Massive production of high and low power electronics devices, specifically designed for e-mobility engines support, starts and new design solutions are explored in order to ensure a good coexistence between them. In particular, the coexistence of Advanced Driving Assistance Systems that implements several radars and sensors, newest communication technologies standards, as CV2-X and 5G, with E-Mobility static energy converter of tens of kW for an EMC Engineer is quite challenging.
In this thesis, the electromagnetic compatibility concepts and the standards, adopted to rule the conducted emission coming from an automotive device, are reported. Then a generic structure of an E-Mobility static energy converter or On Board Charger (OBC) is described and finally the design of an EMI Filter equipped on the OBC is presented, starting from conducted emission measurements test failure, passing through the characterization of the Common Mode Choke, and ending with the simulation analysis and the measurements performed into anechoic chamber.

Abstract
In the last 5 years several automotive company, announced combustion-only engines switch-off production in favor of electrical engines for full-electric or hybrid solutions. Massive production of high and low power electronics devices, specifically designed for e-mobility engines support, starts and new design solutions are explored in order to ensure a good coexistence between them. In particular, the coexistence of Advanced Driving Assistance Systems that implements several radars and sensors, newest communication technologies standards, as CV2-X and 5G, with E-Mobility static energy converter of tens of kW for an EMC Engineer is quite challenging.
In this thesis, the electromagnetic compatibility concepts and the standards, adopted to rule the conducted emission coming from an automotive device, are reported. Then a generic structure of an E-Mobility static energy converter or On Board Charger (OBC) is described and finally the design of an EMI Filter equipped on the OBC is presented, starting from conducted emission measurements test failure, passing through the characterization of the Common Mode Choke, and ending with the simulation analysis and the measurements performed into anechoic chamber.
