    摘要: A system having a noise cancellation converter being configured for phase inverted synchronous operation with a primary converter. The primary converter is operable to supply power to at least one device. The primary converter produces a first electromagnetic interference during operation. The noise cancellation converter is further configured with parasitic components matching parasitic components of the primary converter. The noise cancellation converter produces a second electromagnetic interference that is coupleable to the device. The second electromagnetic interference comprises frequency components having an inverted phase relative to frequency components of the first electromagnetic interference for reducing a sum of the first electromagnetic interference and the second electromagnetic interference during coupling to the device. An RC network component is configured to operatively connect the primary converter and the noise cancellation converter being operable to cancel out the sum of the electro-magnetic interference signals.
