EPS converter
An EPS converter was a component found in the lab aboard Deep Space 9 associated with the station's electro-plasma systems. 

When a harsh noise overwhelmed the lab aboard the station in 2369, Chief Miles O'Brien speculated to Lieutenant Jadzia Dax, who reported the malfunction, that the source might be the EPS converter, Dax explained she already had checked it, and confirmed that it was not the source of the problem.
