| Abstract |
The requirements for the electromagnetic noise
interference (EMI) suppression are stringent necessitating the
use of input filters in switched-mode converters. The EMI filter
may affect adversely the stability and performance of the
associated converter. The methods for EMI filter design have
been laid down in early seventies but not fully understood
among the practicing engineers and scholars. This paper will
provide a general formalism to analyze the EMI filter
interactions based on two-port modeling technique. It is shown
that the behavior of the open-loop input impedance, and the
input-to-output transfer function would provide the
explanations for the differences in the interactions within
different converters. |
