EMI in DC-DC converters...How do we eliminate?

Power supplies are natural generators of narrow-band noise, present at the fundamental of the switching frequency and its associated harmonic frequencies. To contain the noise, it is critical that designers identify its source and the paths it takes in becoming radiated or conducted emissions. Direct radiation of noise can be stopped with simple measures such as enclosing the supply in a metal box or spray coating the case. Designers also need to pay attention to the internal layout of the supply and the wiring that goes in and out of the supply.

A well-defined procedure for predicting EMI in ac-dc power-supply designs and bringing it within regulatory limits saves time and effort versus the trial-and-error methods that designers may be using.
