Solving EMI for Low Wattage Universal Input Power Supplies (PDF) This paper presents methods and results to solve line conducted electromagnetic interference (EMI) for low wattage universal ac line input switching power supplies. The EMI noise reduction is shown for each technique. Techniques include the use of a common mode input coupled inductor, and X ac line capacitor, hot-to-cold ground Y capacitor, schottky rectifiers, and the use of ferrite beads.
