Study on electromagnetic interference of DC/DC converter used in the EV

Electric Vehicle (EV) is driven by electromotor, whose power comes from vehicle power battery. The advantage of the EV is the mechanical simplicity of the drivetrain, but the electromagnetic interference (EMI) is a difficult problem to solve. This paper first describes the electromagnetic interference (EMI) phenomenon generated by one kind of DC/DC converter, Then analyses the reason of the EMI, and finally puts forward the design optimization direction of EMC from the vehicle.
