Summary:

Due to the transformation of the automotive industry from conventional vehicles to electric vehicles, new challenges have emerged concerning Electromagnetic Compatibility. Though the Radiated Emission limits in global regulation are the same for both types of powertrains of vehicles, however, due to the phenomena of conversion of high voltage to low voltage, rapid charging/discharging, and different components involved in electric powertrain, the Radiated Emission from electric vehicles give a strikingly different trend which is challenging to combat. When compared with the conventional Spark Ignition vehicle, many other electronic components of the electric vehicle stay in the mode of Power ON while in the "Ignition ON" steady state. This resulted in us observing a significant shift in the amplitude and frequency throughout the frequency band of Radiated Emission measurement. This paper presents a comparative analysis of the changing trends of Radiated Emission from Spark Ignition Engine to the electric powertrain in the "Ignition ON" steady state, id est, Narrow Band Emissions. It shall help the electric vehicle manufacturers to understand the underlying aspects of designing electric powertrains to meet Radiated Emission limits
