“…In addition, the shape and nature of the interference signal out of the PLC band, which does not affect the SNR directly, are crucial for its potential impact on communication errors. Therefore, many researchers choose an experimental approach to study the impact of real sources (power electronic converters) on the operation of existing communication systems [13][14][15].…”

Power line communication (PLC) is increasingly emerging as an important communication technology for the smart-grid environment. As PLC systems use the existing infrastructure, they are always exposed to conducted electromagnetic interference (EMI) from switching mode power converters, which need to be tightly controlled to meet EMC regulations and to ensure the proper operation of the PLC system. For this purpose, spread-spectrum modulation (SSM) techniques are widely adopted to decrease the amplitude of the generated EMI from the power converters so as to comply with EMC regulations. In this paper, the influence of a spread-spectrum-modulated SiC-based buck converter on the G3-PLC channel performance is described in terms of channel capacity reduction using the Shannon–Hartley equation. The experimental setup was implemented to emulate a specific coupling path between the power and communication circuits and the channel capacity reduction was evaluated by the Shannon–Hartley equation in several operating scenarios and compared with the measured frame error rate. Based on the obtained results, SSM provides the EMI spectral peak amplitude reduction required to pass the electromagnetic compatibility (EMC) tests, but results in increased EMI-induced channel capacity degradation and increased transmission error rate in PLC systems.

“…High-frequency pulse width modulation (PWM) inverters have been widely adopted in motor drive systems because of their high power conversion efficiency, flexible speed control, and competitive pricing [1][2][3][4] . However, high-speed switching operations generate conducted emissions that can cause potential problems involving electromagnetic interference (EMI) [5][6][7][8][9][10] . These undesirable emissions can be in either differential mode (DM) or common mode (CM).…”

Motor impedance and mode transformation have significant effects on the electromagnetic interference (EMI) generated in motor drive systems. Stator winding faults commonly cause motor failure; however, in their early stages, they may not affect the short-term operation of the motor. To date, EMI noise under the influence of premature stator winding faults has not been adequately studied, particularly the differential-mode (DM) noise due to the common-mode (CM)-to-DM transformation. This study investigates and quantifies the influence of stator winding faults on the motor DM impedance and mode transformation. First, the transmission line model of an induction motor is described based on the scattering (S) parameter measurements of each phase of the motor. It offers the flexibility to emulate different types of stator winding faults at specific locations and various severities, such that the impacts of the faults on the motor DM impedance can be easily estimated. Second, a test setup is proposed to quantify the CM-to-DM transformation due to the stator winding faults. The findings of this study reveal that even the early stages of stator winding faults can result in significant changes in the DM noise.

“…The cable harness provides a main gateway for electromagnetic interference (EMI) in automotive system. The unreasonable electromagnetic compatibility (EMC) design of cable harness will produce EMI to other onboard electronic equipment, bringing great safety risks to the system [1][2][3][4]. Theoretical research and engineering practice indicate that many electromechanical systems cannot satisfy EMC standards, which can be attributed to the EMI generated by cables [5][6][7][8].…”

The random wiring of automotive cable harness makes electromagnetic compatibility (EMC) analysis of the whole vehicle very complicated; thus, this paper proposes a simplification modeling technique to model the electromagnetic (EM) illumination on automotive cable harness. First, the stochastic process theory is applied to determine the cable route in a randomly bundling way. Then, the inductance and capacitance parameters of the cable harness at different location are established according to multiconductor transmission lines network (MTLN) theory. On this basis, the simplification modeling technique is developed to generate the electrical and geometrical parameters of the equivalent cable model. Finally, a model of shielded nine-conductor with randomly twisted and a model of unshielded nine-conductor with stochastic wiring in the vehicle are performed to validate the proposed approach by full-wave simulation. The presented method simplifies the complexity of modeling the complete cable harness significantly with a good accuracy.
