PWM Technology for Common-Mode Noise Reduction

2021
For power electronics converters, common-mode (CM) noise is a relatively independent problem. This chapter focuses on PWM techniques to reduce the CM noise. First, the basic problem of CM noise is introduced; then, several improved PWM strategies are introduced to suppress the common-mode voltage (CMV) amplitude; in addition, to suppress the common ...

Common-Mode Noise Absorption Circuit Using Double-Sided Parallel-Strip Line

IEEE Microwave and Wireless Components Letters, 2021
This letter presents a common-mode noise absorption (CMNA) circuit using the double-sided parallel-strip line (DSPSL). The circuit behaves as a pair of conventional transmission lines (TLs) under differential-mode (DM) excitation.

Mitigation of scintillation noise by common mode rejection

SPIE Proceedings, 2005
There is increasing interest in free space optical communications as an alternative to fibre optics and radio frequency communications, particularly in 'last mile' applications and applications with weight and power restrictions e.g. communications with unmanned aerial vehicles.

Analysis of Common Mode Noise Reduction Mechanism in A Shielded Inductor

2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020
To achieve high power density, a power converter circuit is often operated at high frequency, and fast switching devices are also combined to reduce switching loss. On the other hand, both high frequency and fast switching greatly increases conductive noise amplitude at frequency over several megahertz. Therefore, electromagnetic compatibility (EMC) is

A Cascaded Bridgeless Boost PFC With Low Common-Mode Noise

IEEE transactions on power electronics
The conventional bridgeless boost power factor correction (PFC) rectifier is a “paralleled” type bridgeless PFC structure. Although it has the advantages of small on-state loss, least number of components, and no bridge-arm pass-through risk, it cannot ...

Research on common mode noise evaluation method

2008 IEEE Conference on Cybernetics and Intelligent Systems, 2008
Common mode noise produced in single-phase full-bridge converter with bipolar SPWM is analysized. Common mode noise level evaluation method must be monodromy value and calculated simply in common mode EMI suppression system. The three evaluation indexes of maximal spectrum, average spectrum and common mode noise energy are proposed to express the ...

Common mode noise rejection in measuring channels

Instruments and Experimental Techniques, 2015
There is a solution proposed in this paper to reject common mode noise (caused by potential difference between a sensor and a measurement channel) in measurement channels. Its main idea is to provide power supply of measuring subsystem using either an accumulator or a capacitor, which is periodically charged from the electric network by switching on ...

A Balanced Feedforward Current-Sense Current-Compensation Active EMI Filter for Common-Mode Noise Reduction

IEEE transactions on electromagnetic compatibility (Print), 2020
This paper proposes a balanced feedforward current-sense current-compensation (CSCC) common-mode (CM) active electromagnetic interference (EMI) filter (AEF). The advantages of the feedforward CSCC-type AEF are theoretically demonstrated. The operation of

Common mode noise characteristics of resonant converters

2010 IEEE Energy Conversion Congress and Exposition, 2010
This paper investigates the common mode (CM) noise characteristics of resonant converters. Noise sources of CM EMI in isolated resonant converters were identified and analyzed. The operating point of the resonant converter has significant impact on CM noise of the converter.
