Abstract:
A system for filtering electromagnetic interference (EMI) includes a power source that provides alternating current (AC) power; a load; an active rectifier that converts AC power from the power source to direct current (DC) power for the load; and a filter connected between the power source and the active rectifier, wherein the filter comprises at least one notch filter that filters selected frequencies of EMI generated by the active rectifier.
