Insulation monitoring is essential in maintaining distribution grid reliable operation and common-mode (CM) current is an effective indicator for insulation deterioration of electrical assets. Traditional CM current measurement relies on current transformers or sensors physically connected to transmission buses, which suffers from low accuracy due to ...

Investigation of common mode (CM) impedance : Comparison of pure CM and bulk current injection
2017 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2017The common mode (CM) signal appears equally on both lines of a 2-wire cable not connected to ground. It is expressed mathematically as the average of the two signal voltages with respect to ground. In this paper, two different methods to inject CM signals are presented.

Designing Common-Mode (CM) EMI Noise Cancellation Without Y-Capacitor
APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007It is well known that common-mode (CM) conducted electromagnetic interference (EMI) is caused by the common-mode current flowing through the parasitic capacitance of transistors, diodes, and transformers to ground in the power circuit. We need to attenuate this noise to avoid the interface with the other system.

A Systematic Design and optimization Technique for the Suppression of EMI Common Mode (CM) Noise
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018In this paper, Electromagnetic interference (EMI) Common Mode (CM) noise is analyzed and method for noise suppression has been briefly investigated. An improved systematic design of EMI filter is proposed based on the insertion loss parameter, which take full account of the high-frequency (HF) characteristics. In order to improve the performance of EMI

2017 International Conference on Electron Devices and Solid-State Circuits (EDSSC), 2017
The rise/fall time mismatch in a differential signal is responsible for a serious common-mode (CM) issue in high-speed CMOS serializer/deserializer (SERDES) transmitters (Txs). The non-linear parasitic impedance variations of the switching devices and differences in parasitic impedances in the charging and discharging loop produce deterministic spurs ...

In an input-offline switched-mode power supply (SMPS) system, especially in comparison with the cost of noise reduction, significant EMI improvements can be made by incorporating the additional windings, dV/dt balancing winding (B-Winding) and core cancellation winding (C-Winding) into a transformer. However, it is unclear how these additional windings

Proceedings of the IEEE Internatinal Symposium on Intelligent Control, 2003
Predicting and solving electromagnetic interference (EMI) emissions related to common mode (CM) types in inverter (also, in pulse with modulation (PWM) inverter)-induction motor drive systems requires various frequency-dependent effects to be considered. Thus, the application of filter circuitry to prevent dependency on some parameters of the motor for
