Common-Mode Voltage Reduction for Paralleled Inverters
IEEE Transactions on Power Electronics, 2018This 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 ...

Fourth-Arm Common-Mode Voltage Mitigation
IEEE Transactions on Power Electronics, 2016The 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.

Paralleled inverters with zero common-mode voltage
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This 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.

Mitigation of common-mode voltage in matrix converter
3rd IET International Conference on Power Electronics, Machines and Drives (PEMD 2006), 2006This 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.

High voltage buck converter topology for common mode voltage reduction
APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition, 2002A new DC buck power converter topology to actively reduce common mode voltage applied to the load is presented in this paper. The supply is designed to interface universal input DC-DC power supplies to a rectified 480 VAC (700 VDC) bus. By minimizing the common mode voltage produced, the size and cost of the passive filter elements can be significantly

1999 International Symposium on Electromagnetic Compatibility (IEEE Cat. No.99EX147), 2003
The noise mode conversion on the balanced line from the common-mode to the normal-mode was investigated. Two simple parallel traces with the injected common-mode voltage were considered for the mode conversion. The normal-mode voltage converted was calculated from the eight terminals circuit theory.

Common-mode voltage reduction PWM algorithm for AC drives
2009 IEEE Energy Conversion Congress and Exposition, 2009The impact of common-mode voltage (CMV) generated by pulsewidth modulation (PWM) ac drives on motor bearings is well known. Several algorithms for CMV reduction have been proposed in the literature. While a few algorithms assume ideal switching and fall apart when nonidealities like inverter dead time are considered, some others are effective only in a
