Abstract
An electromagnetic interference (EMI) filter, method of manufacturing therefor and power converter employing the EMI filter. In one embodiment, the EMI filter includes (1) a filter circuit board located outside a chassis and having an aperture that receives therethrough a bus bar extending from within the chassis, (2) a capacitor, mounted on the filter circuit board and coupled to the bus bar, that receives from the bus bar at least a portion of EMI induced into the bus bar from within the chassis and (3) a conductor, mounted on the filter circuit board and coupled between the capacitor and the chassis, that receives the portion from the capacitor and returns the portion to ground via the chassis.
