The present work aims to determine a method for modeling and designing different types of filters that exist between nodes in a single phase topology with BPL technology for housing. The filter design objectives are to control the spectral power density, with the effect of the BPL transmission power is optimized and significant offset voltage variations that occur in the connection and disconnection of electric charges, both effects are presented in a phase topology that is used as the communication channel. The results are reflected in the attenuation of electromagnetic compatibility (noise, attenuation, distortion, and coupling) relevant variables that cause problems on the communication channel of a system with BPL technology.
