(TU Delft DC systems, Energy conversion & Storage) Qin, Z. (TU Delft DC systems, Energy conversion & Storage) Bauer, P. (TU Delft DC systems, Energy conversion & Storage) Date 2020 Abstract A voltage imbalance at the AC terminals of a three-phase inverter creates a ripple in the power signal on the DC side. In order to minimize this ripple, several techniques can be applied, in which a double Synchronous Reference Frame (SRF) current control structure is very typical. In this approach, both the positive and negative sequence currents are controlled. This technique has been shown to have an adequate response against imbalances; however, this paper shows that in the typical implementation of the double SRF control, the output AC pq instantaneous powers will have a constant error due to the phase-angle misalignment of the negative sequence with the positive sequence. Based on mathematical formulations and simulation results, this paper shows that this AC-power error exists, and that it is due to the above reason. In order to overcome this, this paper proposes to have a phase-tracking system that specifically follows the negative sequence phase-angle. The results show that this implementation is able to properly control the output AC power.
