Abstract
A system having ring generation device being configured for phase inverted synchronous operation with a primary converter device. The primary converter device is operable to supply power to at least one device. The primary converter device produces a first electromagnetic interference during operation. The ring generation device produces a second electromagnetic interference that cancels the first electromagnetic interference. The primary converter device and the ring generator device are synchronized and operate in an inverse phase with each other to generally cancel the electro-magnetic interference signal created by the primary converter device. A ring generation charging switch and a ring generation discharging switch generally turns on and off alternately which matches a charging and discharging of a primary switching node.
