Input Impedance Characteristics of an Electronic Choke - Influence by Inductor with Different Winding Structure

In our original wire communication system, an electronic choke is built into each terminal. The electronic choke composed of two small inductors and an amplifier has high input impedance. In the powered terminal, the ac communication signal and the dc power can be separated. To be suitable for the communication frequency use, we should select the inductors of the electronic choke. In the absolute value of the input impedance frequency characteristics of the electronic choke, two peaks appear. These two peak frequencies are adjusted by the communication frequency that we want to be used. In this paper, we investigate the influence of the input impedance frequency characteristics of the electronic choke on the peaks frequency by the inductor with different windings structure
