What are European electromagnetic requirements?
What are FCC electromagnetic requirements?
Electromagnetic compatibility (EMC) has become a major challenge for equipment and switching power supply designers. As more and more countries apply EMC regulations on products entering their respective markets, EMC compliance of a product has become a major factor defining its acceptance.
The EMC challenge has two parts:
1. Suppression of interference at the source
2. Making devices or systems immune to EMI
There are three general approaches to suppressing of EMI:
1. Good screening for radiated EMI
2. Proper earthing
3. Filtering of power an signal lines to reduce conducted EMI
