摘　　要：低压电力线作为载波通信信道时,其通信特性并不理想,各种负载、用电设备及外界都将引起大量的噪声,给电力线载波通信带来了严重的干扰问题,从而影响电力线通信系统的性能。为了保证载波通信信号和数据的有效传输,通过电路分析并设计一种低压电力线载波通信结合滤波器,经仿真与实验该滤波器能有效过滤低压电力线载波通信信道中的各种干扰信号,从而达到了保证载波通信信号和数据的有效传输的作用。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 cou piing 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.
