Why Call EMI Filters Black Magic?
Most engineers, both designers of electromagnetic interference (EMI) devices and
others, call EMI black magic. There are four main reasons for this. First, there
has not been a well-defined design method. Second, the input and output
impedances are not constant over the band of interest. The impedances are usually
just good guesses, at best, because the measurements are costly to make and are
rarely repeatable. Third, the filter insertion loss test method specifications often
confuse or influence the design method. In the 220A specification, requiring
50-ohm source and load impedances, does the filter engineer design the filter for
the 50 ohms or for real-world impedances? If the design passes the Military
Standard (MIL STD) 220A, 50-ohm, test, what will happen in the real world? Is it
the designer’s responsibility to meet the specification or to stop the real-world
emissions? Fourth, the design methods outlined in various publications are
generally very complex. Most require measurements that are difficult to make and
time consuming. Often expensive additional equipment is required to obtain the
needed parameters.
1.1. WHAT IS EMI?
EMI is electromagnetic interference and is called conducted emissions or radiated
emissions. This book covers mainly conducted emissions (CEs), which means any
unwanted signal or noise on the wiring or copper. The reason for the reference to
power cabling is that EMI filters are part of the power wiring and are designed
to remove these unwanted properties from the copper wiring. Why is this from
the wiring? What does this have to do with magnetic fields? The reason is that
