A systematic parameter tuning of PI current controller for LCL-type active rectifiers under unbalanced grid voltage conditions

A systematic parameter tuning of PI current controller for LCL-type active rectifiers under unbalanced grid voltage conditions

Active rectifiers are widely employed in three-phase electric drive or renewable energy resource systems because of the bidirectional power flow and the power factor correction. This paper proposes a systematic method to determine the parameters for the PI current controllers in active rectifier sys...
