Abstract
An apparatus and a method of electrically filtering unwanted noise signals between a computer sub-system and a power sub-system is disclosed. The computer sub-system and the power sub-system are housed within an electrically conducting housing which includes a partition between the computer sub-system and the power sub-system. The apparatus includes a bus bar connected between the power sub-system and the computer sub-system for providing direct current energy between the power sub-system and the computer sub-system. A dielectric material encompasses the bus bar. An electrically conducting material encompasses the dielectric material and is connected to the electrically conducting housing. A virtual capacitor is thereby formed between the bus bar and the housing, providing a path of least resistance for the unwanted noise signals.
