Features of Power-Line Impedance Effects on EMI Filter Performance

摘要

This paper presents the effect estimation of power-line impedance on the filter performance at a frequency range from 9 kHz to 30 MHz. In this paper proposed the requirements for microprocessor control to determine the power-line impedance in real-state to following changes for EMI filters, On the basis of analysis of known methods of power-line impedance determination developed algorithm for CPU of EMI filter operation.
