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,

Common-Mode Voltage Reduction for Paralleled Inverters

IEEE Transactions on Power Electronics, 2018
This paper introduces series work of common-mode (CM) voltage reduction for the paralleled inverters. The paralleled inverters’ phase-legs are connected through coupling inductors and the combined three-phase currents are provided to the load. Interleaving is an approach to reduce the CM voltage for the paralleled inverters but it cannot eliminate CM ...

Study of Common-Mode Voltage Measurements for IEC62684

IEEE Transactions on Industry Applications, 2013
This paper presents the study of common-mode (CM) voltage measurements for IEC62684 regulatory. Due to the digitization error caused by the limited vertical bit number of the analog-to-digital converter (ADC) in oscilloscopes, the CM voltage spectrum measurement of the flyback converter with AC source occurs significant inaccuracy.

Common-mode voltage in matrix converters

4th IET International Conference on Power Electronics, Machines and Drives (PEMD 2008), 2008
In this paper, the triple common-mode harmonics of matrix converter, introduced by space vector modulation, are systematically investigated. Several switching patterns such as three-zero, two-zero, one-zero and optimised one-zero are analysed.

An approach to reduce common-mode voltage in matrix converter

IEEE Transactions on Industry Applications, 2003
In this paper, an approach to reduce common-mode voltage at the output of a matrix converter is discussed. A new modulation strategy which reduces the common-mode voltage at the output is presented. The proposed method maintains the active voltage vector and distributes zero vector equally within a sampling period and reduces square RMS of ripple ...

Common mode voltage to differential mode voltage conversion characteristics of shielded transformer in VHF band

Asia-Pacific Conference on Circuits and Systems, 2003
This paper describes the noise suppression characteristics of an isolation transformer with an electrostatic shield in the VHF band. Several experimental results are described and the analysis of several characteristics using an equivalent circuit of the transformer is shown. The following two characteristics are investigated.

Fourth-Arm Common-Mode Voltage Mitigation

IEEE Transactions on Power Electronics, 2016
The adverse effect of common-mode voltage (CMV) in pulse-width modulation inverters is widely acknowledged. Various approaches for mitigating CMV effect in PWM inverters have been proposed in the literature but they either show limited effect or impair the utilization of the drive.

Mitigation of common-mode voltage in matrix converter

3rd IET International Conference on Power Electronics, Machines and Drives (PEMD 2006), 2006
This paper presents a new modulation scheme for matrix converters. With the proposed method, the peak common mode voltage is reduced to 1/√3 of the input phase voltage amplitude; at least 2/3 reduction in the high order harmonics and 1/3 in RMS value are realised. Indirect space vector modulation is adopted and modified.

Paralleled inverters with zero common-mode voltage

2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016
This paper introduces a PWM method for paralleled inverters which can achieve zero common-mode voltage. The paralleled inverters are connected through coupling inductors to the load. Based on the voltage vectors in each inverter, paralleled voltage vectors are proposed to combine the reference voltage.
