Design of a parallel active common mode current compensation circuit

2012 IEEE International Symposium on Industrial Electronics, 2012
a parallel active common mode current suppression scheme is present. Two different compensation circuits, which are direct parallel and indirect parallel compensation circuits, are introduced in this research. The common mode current equivalent model of the single-phase half-bridge inverter with two different compensation circuits is studied.

Origin and propagation of common mode currents occurring in a bridge rectifier

Proceedings of Intelec 93: 15th International Telecommunications Energy Conference, 2005
The aim of this paper is to investigate the generation of common mode currents in an AC/DC power converter, in particular a silicon controlled rectifier (SCR). In fact, this paper is intended to be a first step to understanding radiated electromagnetic noise emission from an SCR and to localizing its cause and place of origin.

Impact common mode currents on miniaturized UWB antenna performance

2005 European Microwave Conference, 2005
The main goals of this article are investigation of impact of parasitic (common mode) currents on UWB antenna performance and study on possible designs of UWB baluns. This research is carried out on one of popular designs of UWB antenna for impulse radio, namely elliptically shaped dipole.

Differential amplifiers that reject common-mode currents

IEEE Journal of Solid-State Circuits, 1971
The transistor differential pair is analyzed and it is shown that the common mode rejection ratio (CMRR) is limited both in magnitude and bandwidth by device parameters. The performance is not significantly improved by series common-mode feedback. It is shown that amplifiers with shunt common-mode feedback reject common-mode input currents and that ...

Common mode current characteristics in transmission line with common mode choke represented by two-port chain matrix

Asia-Pacific Conference on Circuits and Systems, 2003
For common mode noise current reduction, a common mode choke (CMC) is widely used in a transmission line. However, the characteristics of common mode noise current reduction have not been clearly analyzed yet in the case where a CMC(s) is inserted in a balanced transmission line.

Common-Mode Current Suppression of Transformerless Nested Five-Level Converter With Zero Common-Mode Vectors

IEEE Transactions on Power Electronics, 2019
Three-phase transformerless multilevel converters are widely used in the high-voltage photovoltaic power generation systems because of their low total harmonic distortion, high power density, and high conversion efficiency. One three-level flying capacitor converter and dual T-type three-level circuits can be combined to derive the compact and cost ...

Common mode current and radiations mechanisms in PLC networks

2007 IEEE International Symposium on Power Line Communications and Its Applications, 2007
This paper presents the results of a three-year, in-depth study of the mechanisms of EMC emissions generated by an in-house PLC network. The study was led in close collaboration with the Institute for Information and Communication Technologies, the Swiss Federal Office of Communication and, in the framework of the OPERA project, with the EMC team of ...

LCL and Common Mode Current at the Outlet Do Not Tell the Common Mode Current Generated at the Remote Unbalanced Element on the Power-line

2009 20th International Zurich Symposium on Electromagnetic Compatibility, 2009
The radiated emission from the power-line communications (PLC) is primarily caused by the common mode (CM) current converted from the differential mode (DM) current at the remote unbalanced elements (RUE) distributed on the power-line. The LCL measured at the outlet (outlet LCL) is often used as a measure of the unbalance despite the negative results ...

Protection against common mode currents on exposed cables

2015 IEEE International Symposium on Electromagnetic Compatibility (EMC), 2015
Above deck cables on naval ships are exposed to High Intensity Radiated Field (HIRF) that may cause conducted interference and generate electromagnetic fields that exceed the immunity levels of commercially available equipment in the protected environment below deck.
