4EMI Filter Source Impedance of Various Power Lines
One of the leading questions asked by people who have EMI issues or who are joining the EMI field is related to source impedance and how this affects the frequency magnitude response of the EMI filter. Engineers who have experience with EMI filter design will want to have a good approximation of an EMI filter’s transfer function H(s) that is being used in their application. This is also true if the filter is being developed by a third party. The reason behind this is to ensure that the filter is optimized for stability. Even if a filter is developed by a third party, it is possible to determine an accurate equivalent two-port transfer function that should yield half-power bandwidth, frequency ...
