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

The present work describes the behavior of different power converters of a distributed power system in the generation and emission of conducted electrical noise (EMI). The effect of some internal factor designs on the measurement of conducted electrical noise in an AC power line has been analyzed. As a result, the authors describe 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 fulfilment the limits imposed in the conducted noise levels by the European Norms on electromagnetic compatibility (EMC)
