Introduction to EMI in power supply designs

The The design design approaches approaches covered covered include include matrix matrix methods methods using using table table data data and and the the use use of of Fourier Fourier analysis, analysis, Laplace Laplace transforms, transforms, and and t

To suppress diferential-mode currents we can add large diferential mode capacitors as described previ-ously (use “X” capacitors for ac-line applications). The leakage inductances from the common-mode choke can form some or all of the diferenti

Essentially, an EMI filter is made up of two basic types of components–capacitors and inductors. The simplest type is called a first-order filter consisting of just a single reactive component. Capacitors shunt noise current away from a load while i
