“…Then, numerical fitting algorithms are applied to identify the analytical rational function. The extracted rational function can be represented by π subcircuits of either RLC lumped elements or Laplace elements [77]. As the number of computation cells builds up for longer cables, the computation burden increases.…”

Electromagnetic interference issues are associated with high-speed switching of power converters. EMI modeling is an essential tool to study and control the EMI emission, enabling more efficient solutions. A comprehensive review and comparison of different modeling approaches for conducted emissions are provided in this paper, which can be used as a design guideline for engineers. For a motor drive application, common mode and differential mode conducted emissions are studied, and dominant noise production mechanisms are identified. Moreover, a review of various modeling techniques is presented for the main parasitic components of the system. Finally, time domain and frequency domain analysis approaches are explored along with the equivalent circuits which enable fast prediction of EMI emissions. This paper intends to help the reader develop an organized understanding of conducted emission modeling to assist them with a more efficient and electromagnetically-compatible design. INDEX TERMS Circuit modeling, common mode, conducted emission, differential mode, electromagnetic interference (EMI), motor drive inverters.

This paper presents an impedance-based modelling method for length-scalable long transmission cable (LTC), which is able to assess influence of LTC on stability of grid-connected inverter (GCI). Electrical parameters of power cable in perunit-length (p.u.l.) are first extracted from the measured terminal short-circuited and open-circuited admittances. Then, the terminal admittance of power cable in different length can be derived on the basis of the obtained p.u.l. parameters. Finally, a decoupled two-port circuit model is established for the LTC using the derived terminal admittance. Simulation results are given to validate effectiveness of the proposed impedancebased modelling method for LTC. The proposed impedancebased modelling method is able to avoid repetitive terminal impedance measurement. Also, the proposed model is able to support impedance-based stability criterion for GCI with lengthscalable LTC. Index Terms-Grid-connected inverter, impedance-based stability analysis, long transmission cable, p.u.l. parameters, twoport circuit.

“…However, the measurement of terminal impedance frequency responses of the LTCs can be tedious and time‐consuming, if many LTCs exist in the OWPP. In [40, 41], the frequency‐dependent p.u.l. electrical parameters of the power cables are extracted from measured terminal impedance frequency responses of a specific power cable, and used to calculate the terminal impedance formulas of the same type of power cables in other lengths.…”
