It's well known that a switched-mode power supply is easily to produce electromagnetic radiation emission and often fails in EMC test for its RFI exceeding limits between 30MHz-100MHz. The accurate radiation emission prediction technology is very helpful to a SMPS designer to find the potential problems at earlier stage and remove them in advance. This paper proposes a novel time domain simulation method, electromagnetic field-circuit collaborative strategy (FCS), to predict the far-field radiation emission of a Buck converter. The feasibility and deviation of this method are analyzed firstly. Then a buck converter is modeled and simulated to predict its EMI source and far-field radiation emissions. The effectiveness of this method is verified by comparing the prediction results and the experiment results.
Keywords:RFI prediction, field-circuit co-simulation, SMPS
