Prediction of Common-Mode Radiated Emission of PCB with an Attached Cable Using Imbalance Difference Model

The miniaturization and integration of Switching Mode Power Supply (SMPS) is increasing, making it more complicated to analyze and predict its far-field radiated emission, and, consequently, studying the suppression method of far-field radiated emission of SMPS is of practical significance and engineering value. In this paper, a high-frequency SMPS is selected as the research object, whose far-field radiated emission is measured under the condition of three typical suppression methods. The experimental results verified the effectiveness of common-mode inductor and are of reference value for EMC design of power converter. Keywords: SMPS; EMC; Far-field Radiated Emission;

Radiated Emission

The strong electromagnetic interference produced by the electric drive system is the main factor that leads to the strong radiated emission of electric vehicles. It is very important to study the influence of the electric drive system on vehicle-radiated emission by taking the common-mode current of the electric drive system as the interference source. In this paper, the conducted emission model of the electric drive system is proposed, and the common-mode current is calculated by this model. The influence of filter on the common-mode interference current of HVDC cables is calculated and analyzed, and then the radiating antenna effect model of HVDC cables is established. Based on this, a vehicle-level radiated emission simulation model including an electric drive system and DC cables was established. The effectiveness of the conducted emission model was verified by experiments. The effects of different shielding structures on the shielding efficiency of HVDC cables were compared. Quantitative guidance for EMI suppression design of multi-in-one electric drive system design can be provided by the model in this paper.
