Grid-Following Voltage Source Converter With a PLL-Less PI Passivity-Based Controller for Unbalanced Grid Conditions

IEEE transactions on power electronics
Actual voltage-source converters (VSCs) advocate flexible and fast controls, low-voltage ripple levels at the dc-link, and grid compliances for operating under imbalanced grid conditions. To counteract these needs, this investigation focuses on proposing
