| 摘 要： | 针对电力线通信中LC无源滤波器体积大、元件参数不易确定等问题，阐述了利用GIC设计椭圆低通和高通滤波器的方法。利用Filter Solutions软件设计归一化椭圆低通滤波器，用GIC代替D元件或电感，经过频率变换和阻抗变换，得到实际的低通或高通滤波器。经过仿真，滤波器达到设计指标。该设计方法在某电力线载波通信门禁系统得到应用，使112～114 kHz的载波信号被完整提取，保证了系统的完整性能。

| Abstract: | In view of the problems in the power line communication that the LC passive filter volume is big,the component parameter is not easy to determine,and so on,the method to design elliptic low pass and high pass filters using converter(GIC)is introduced.First,the Filter Solutions software is used to design normalized ellipsed low pass filter,then the D part or the inductance is replaced by GIC,after the frequency transformation and the impedance conversion,the actual low pass filter or high pass filter is obta... |
