Abstract
This paper represents the conducted electromagnetic interference (EMI) characteristics of the electric drive system in electric vehicles, based on the typical vehicle driving circles. Firstly, the typical vehicle driving circles are introduced, such as Economic Commission of Europe-15 (ECE-15), Extra Urban Driving Cycle (EUDC) and so on. Also, the relationships between motor speed, torque and vehicle speed are calculated according to the mechanical properties of the vehicle. Then, the simulation and experiment platforms are established considering the motor speed and torque as reference inputs. Finally, the dynamic EMI of power electronics device switching processes, system dynamic differential mode (DM) and common mode (CM) EMI are analyzed through the simulation and experiment results.
