An optimal zero‐sequence voltage injection‐based common‐mode voltage reduction pulse‐width modulation for the reduction of common‐mode voltages in both amplitude and third‐order component

IET Power Electronics, Volume 15, Issue 14, Page 1480-1489, 4 November 2022., 2022
Abstract An optimal zero‐sequence voltage injection‐based common‐mode voltage reduction pulse‐width modulation (CMVRPWM) for the reduction of common‐mode voltages (CMVs) in both amplitude and third‐order component is proposed in this paper. On the basis of general symmetrical switching patterns of CMVRPWM, a constrained mathematical programming model ...

A Review of Control Techniques and Energy Storage for Inverter‐Based Dynamic Voltage Restorer in Grid‐Integrated Renewable Sources

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Power quality (PQ) is a key issue, particularly for technologically advanced process equipment, whose performance mainly depends on the quality of supply. Problems with PQ such as voltage swells/sags, interruptions, and harmonics are defined by any voltage, current, or frequency abnormalities causing damage or failure of the end‐user equipment. Outages

Neutral‐Point Potential Balance Control Strategy on Three‐Level Active Power Filters

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
This paper presents a simplified strategy in neutral‐point (NP) potential balance of the neutral‐point‐clamped (NPC) three‐level three‐wire active power filter (APF). By introducing a simplified carrier‐based pulse width modulation (CB‐PWM) strategy and analysing the occurrence mechanism of NP potential unbalance, we proposed a NP potential balancing ...

Model Predictive Control Method with Constant Switching Frequency to Reduce Common‐Mode Voltage for PMSM Drives

Journal of Electrical and Computer Engineering, Volume 2018, Issue 1, 2018., 2018
A model predictive control method to reduce the common‐mode voltage (MPC‐RCMV) with constant switching frequency for PMSM drives is proposed in this paper. Four nonzero VVs are adopted in future control period and the switching sequence is designed to ensure the switching frequency is fixed and equal to the control frequency. By substituting the finite‐
