An Improved Three-Phase Voltage Source Converter With High-Performance Operation Under Unbalanced Conditions

IEEE Access, 2018
The unbalance of the three-phase grid-voltages/loads can cause double-frequency power ripples in the voltage source converter (VSC) system. Such power ripples can further lead to current and/or voltage ripples on the dc link, which may create instability
