印刷电路板的电磁辐射研究
【摘要】:The electromagnetic radiation of PCBs is analyzed and the EMC modeling is submitted on the basis of the electric dipole, the magnetic dipole, theory of the travelling-wave currents, theory of common-mode/different-mode currents and the theory of mirror currents in the frequency domain and the time domain. Applications of common-mode check coils are discussed. The radiated fields of DVB-s2000 are measured and the data are analyzed.
