How to Reduce EMI in Switching Power Supplies (.PDF Download)

Modern electronic power system architectures are becoming denser with a huge amount of interconnections. And reducing EMI in these kinds of systems is becoming increasingly challenging.

One of the top EMI offenders is the switched-mode power supply (SMPS). It can reside externally from a system design or printed circuit board (PCB) or it may be a part of a design on a PCB. Either way, EMI mitigation must be reduced in order to pass standards tests as well as operate surrounding circuitry without errors. This article will provide circuit designers with some of the best methods to control EMI in their designs.
