Measurement and correction of conducted electrical noise in distributed power supplies (1kW) with power factor corrector

The present work describes the behavior of different converters of a Distributed Power System in the generation and emission of conducted electrical noise (EMI). It has been analyzed the effect of some internal factor design in the measurement of conducted electrical noise in an AC power line. As a result, we will described some of the factors that affect the conducted electrical noise, as well as some simple solutions to be included into the designs. They have to be used to fulfillment the limits imposed in the conducted noise levels by the European Norms on Electromagnetic Compatibility (EMC).
