Abstract

A broadband RFI power line filter in which emission filters designed for the 10 KHz to 30 MHz range are combined with high frequency filter elements so as to produce a filter in the 10 KHz to 1000 MHz range. The filter is divided into sections which are constructed in separate electrically isolated compartments so as to increase the attenuation which can be obtained with filters which are not separated from each other and electrically shielded compartments and the level of attenuation which must be achieved from each compartment is reduced in the invention.
