A Zoning Impedance Modeling Method Based on Multi-port Devices

Aiming at the modeling problem of the equivalent impedance circuit of complex multi-port devices containing multi-core cables, this paper presents a method of zoning impedance modeling based on multi-port devices. In this paper, based on the circuit resonance mechanism, RLC resonant element is used for sectional impedance curve fitting to establish the complete impedance equivalent circuit model. The simulation results show that in the general frequency band of 150kHz∼30MHz, the simulation curve fits well with the measured curve.
