An Enhanced Control Strategy for AC–DC Matrix Converters Under Unbalanced Grid Voltage
IEEE transactions on industrial electronics (1982. Print), 2020Under unbalanced grid voltage conditions, an ac–dc matrix converter (MC) induces ripple on the dc side, as well as severe grid current harmonics. To overcome these problems, an enhanced control strategy for an ac–dc MC based on an independent control ...

This paper proposed a modified predictive direct power control (P-DPC) strategy for a grid-connected voltage-sourced converter under unbalanced grid voltage conditions. The proposed P-DPC strategy is implemented in the stationary reference frame without the necessity of either the space vector modulation or the synchronous speed d-q transformation.
