Common-mode and differential-mode analysis of common-mode chokes

open access: yes2003 IEEE Symposium on Electromagnetic Compatibility. Symposium Record (Cat. No.03CH37446), 2004
In this paper, three methods for the measuring common-mode and differential-mode S-parameters of common mode chokes are presented. The three methods involved: (1) ABCD chain matrix; (2) using hybrid couplers; and (3) modal decomposition. Each measurement method provides a specific level of accuracy. The modal decomposition method can work up to 10 GHz.

Common-Mode Capacitance of Bus-Bar-Based Common-Mode Inductors

open access: yes2021 IEEE Electric Ship Technologies Symposium (ESTS), 2021
Prediction of the common-mode self-capacitance of common-mode inductors is essential to their design in order to ensure effective operation over the frequency range of interest. This paper presents a model for the calculation of common-mode capacitance of a bus-bar-based common-mode inductor. An equivalent circuit of the inductor that accounts for high-

LOW POWER CONTINUOUS TIME COMMON MODE SENSING FOR COMMON MODE FEEDBACK CIRCUITS

open access: yesJournal of Circuits, Systems and Computers, 2010
Continuous common mode feedback (CMFB) circuits having high input impedance and low distortion are proposed. The proposed circuits are characterized for 0.18 μm CMOS process with 1.8 V supply. Simulation results indicate that the proposed common mode detector consumes no standby power and CMFB circuit consumes 27–34% less power than previous high ...

Common-Mode Voltage Cancellation for Reducing the Common-Mode Noise in DC–DC Converters

IEEE Transactions on Industrial Electronics, 2021
Common-mode (CM) noise cancellation method is an attractive approach to reduce the original CM noise in power converters, which helps to shrink the size of electromagnetic interference filter. Traditional CM noise cancellation method cancels the CM noise current by adding a branch consisted of a compensation voltage source and a compensation capacitor,

Methodology for the Common Mode Analysis

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">The assumption usually made in the safety analysis of most systems is that the failure of any one component is independent of the failure of any other. If this assumption is not valid due to the system design and implementation, the estimated Fault Tree Analysis (FTA) event probabilities will be more optimistic ...

On the measurement of common-mode rejection ratio

IEEE Transactions on Circuits and Systems II: Express Briefs, 2005
In this brief, several commonly used measurement configurations for common-mode rejection ratio (CMRR) are analyzed and compared with the definition; their advantages and limitations are also discussed. Finally, an improved measurement setup is proposed to characterize CMRR more accurately according to its definition over wider frequency range.
