EMC/EMI

EMC/EMI covers all issues related to passing an emissions or susceptibility certification test. This includes topics related to the test specs, shielding, spectrum control by filtering or clock modulation, the use of ferrites, return path control, suppressing plane resonances, antenna design, sources of ingress and egress of radiation, and use of special materials.

Tools to Combat Radiated Emissions, for EMC Compliance and Performance Gains

New power-semiconductor technologies like SiC and GaN enable increased efficiency and higher switching frequencies, which allows smaller component sizes. But these gains come at the expense of greater radiated electromagnetic emissions, just as EMC regulations are getting tougher. How can engineers effectively minimize radiated EMI?
