- Robust operation of Voltage Source Converters under unbalanced voltage dips can be obtained by controlling the positive and negative-sequence currents separately with a Dual Vector Current Controller (DVCC). In this paper, the performance of the DVCC is investigated under all voltage dips that can affect the converter. Two different methods for taking into account the oscillating powers dissipated in the filter are presented, tested and compared. The effect of the phase-angle jump of the dip is also studied.
