摘要：
Radiated electromagnetic interference (EMI) is an important and challenging topic in modern power electronics. To analyze radiated EMI, modeling research is the foundation. Modeling research can reveal fundamental mechanisms including switching noise generation, noise conversion into the radiation excitation, antenna characteristics, and near field couplings' impact. Radiated EMI models are developed. Based on radiated EMI modeling research, noise reduction techniques are developed, including component improvement, printed circuit board (PCB) layout improvement, high-frequency EMI filters, and shielding. This paper summarizes recent research advances and discusses future radiated EMI challenges and research topics.
