Liu Xiang-peng · Electric Drive · 2011
According to the EMC issues which should be considered in design stage of switched mode power supply,to predict the conducted EMI in design stage,locate the influences in the propagation of SMPS,methods of frequency simulation and parasitic extraction of PCB and SMPS structures as well as design principles of PCB and structures of SMPS were introduced.The problems in the prediction process must be pad attention to and the strategies used to reduce the conducted EMI of SMPS were analyzed and summarized.
