| Abstract: | Because of the low-voltage power line as a data communication channel,its communication features are not satisfactory,and various loads,electrical equipments and environment cause a lot of noise,which affect the power line communication system performance.In order to ensure the effective transmission of the carrier communication signal and data,a coupling filter for low-voltage power line carrier communications is designed through the circuit analysis.The simulation and experimental results show that this coupling filter can effectively filter various interference signals in the low-voltage power line carrier communication channel,and thus realizes the function of effective transmission of carrier communication signals and data. |

| Keywords: | low-voltage power line carrier communication coupler low-pass filter band-pass filter |
