Runo's Power Design
It is a well known fact that SMPS circuits usually cause trouble with electrical
Electrical interference is often
conceived as something mysterious or inscrutable. It does
not have to be so. Electrical noise obeys well known
physical rules - it just may be hard to see.
Some kinds of electrical noise are so predictable that a noise spectrum can be calculated, however most kinds of noise are not easy to predict accuratly. Measurements and experiments are the best tools here.
For the measurement of conducted emission I use a home built LISN network which can pick out the noise for each conductor separately, but further it can separate the Common Mode and the Differential noise parts. This property has no relevance at an approval test, but for the design engineer it is indispensable since the origins of these two noise forms are different, and so are the appropriate solutions.
