摘　　要：电力线通信技术创新的应用于智能家庭网关设备中,通过光纤传输作为上行接入媒介,通过电力线实现下行端口数据的入户传输。目前宽带电力线通信技术的传输瓶颈在于入户220 V AC电路回路的干扰,电力线通信设备对电源端口的浪涌防护要求高于普通入户设备,为了避免端口受到浪涌破坏,在不引入电力线干扰、不影响设备通信性能的前提下分别从差模与共模两种情况设计防护电路,通过实验验证及仿真结果表明所设计电路符合要求。Power line communication technology is innovatively applied to smart home gateway equipment by using optical fiber transmission as the uplink access medium;and the home transmission of the downlink port data through the power line is realized.At present,the transmission bottleneck of broadband power line communication technology is the interference of 220V AC circuit loops at home.The power line communication equipment's surge protection requirements for power ports are higher than ordinary home equipment.On the premise of not affecting the communication performance of the equipment,the experimental verification and simulation results show that the designed circuit meets the requirements.
