摘　　要：基于直流电力线通信(Direct Current-Power Line Communication,DC-PLC)技术构建信道集总参数模型,推导直流电力线信道阻抗与耦合变压器最佳匝数比之间的数学关系,设计了一种窄带DC-PLC可调阻抗匹配耦合器调节方案,可满足大多数阻抗匹配的要求,同时提供多个可供选择的匝数比。仿真结果表明,可调阻抗匹配耦合器可以动态调节匝数比。Based on Direct Current-Power Line Communication(DC-PLC) technology, this paper constructs a channel lumped parameter model, and deduces the mathematical relationship between DC power line channel impedance and the optimal turn ratio of coupling transformer, then a narrow-band DC-PLC adjustable impedance matching coupler adjustment strategy is designed, which can provide multiple alternative turn ratios while meeting most impedance matching requirements. The simulation results show that the adjustable impedance matching coupler can dynamically adjust the turn ratio.
