“…11, the multi-physics platform includes correlations between different sub-systems in AN-SYS Software. Accordingly, a DC-choke with a frequencydependent core material solved in ANSYS Maxwell [8], a parasitic model of AC machine [16], and the proposed cable solved in ANSYS 2D Extractor are all linked to ANSYS Simplorer for the time-domain analysis. Moreover, the parameters of the drive are depicted in Table II.…”

“…Recently, due to the growing tendency to increase the switching frequency of the power converters, parasitic couplings of the cables can significantly affect the Electromagnetic Compatibility (EMC) performance in the drive systems [5]- [7]. In fact, power cables can significantly reduce the CM impedance seen from the motor side, making the system more susceptible to Electromagnetic Interference (EMI) emissions [8]. Due to the frequency-dependent characteristics of permeability, permittivity and skin depth, simple cable models are not able to achieve high accuracy [9].…”

This paper proposes a practical method to model the Common-Mode (CM) impedance of power cable in Finite Element Analysis (FEA) software. The proposed approach utilizes a reverse-engineering method to estimate the frequencydependent characteristics of the cable materials. Accordingly, two experimental measurements are proposed to calculate the parameters of the cable assumed from a basic lumped-π model. Then the material specifications of the cable PVC are estimated in the FEA software. The results verify that the the proposed model can predict the CM impedance of the cable with a great accuracy in a wide frequency range. This approach is highly practical and convenient, which can be readily extended to different kinds of power cables, ensuring high accuracy at a wide frequency range.

Magnetic chokes are conventionally utilized at the DC or AC side of the Adjustable Speed Drives (ASDs) to suppress low order harmonics of 0-2 kHz. Recently, the frequency range of 9-150 kHz has been noticed as a new disturbing frequency range, interfering with the distribution networks. Due to the novelty of this topic, so far, there has not been a thorough investigation for the effect of DC and AC choke configurations on 9-150 kHz emissions, especially for the three-phase ASDs. In this paper, the effect of DC and AC choke configurations on Common-Mode (CM) current emissions at the frequency range of 9-150 kHz is broadly surveyed in the three-phase ASDs. Subsequently, the comprehensive equivalent models of the system are presented for each configuration of DC and AC chokes. This investigation is based on the comparative analysis of the system's transfer functions according to the presented single-phase equivalent model, mathematical calculations, and the three-phase system circuit. Consequently, the presented approach is highly useful to minimize the drive system volume, as the designer can predict the choke configuration of the smallest size for suppressing 9-150 kHz emissions.
