Preventing Conducted and Radiated EMI in Switching Power Supplies (Download)
Electromagnetic interference (EMI) is one of the most damaging and disturbing causes of diminished performance in electronic and electrical devices. Data will be compromised and can even be lost, thus wreaking havoc within most electronic systems.
EMI can be in the form of non-contact radiated (via induction) through the air and/or conducted via direct physical contact, such as with cabling.
