Modern power supplies need to reduce power loss to maintain a high degree of efficiency. Switch mode power supplies and DC/DC switching controllers are state of the art and allow great efficiency, but if the design of the circuit and circuit board layout is less than ideal this can result in increased emission of radio interference voltage. This article discusses the systematic implementation of input filters for reducing symmetric interfering voltage in DC/DC switching controllers.
