    This paper presents an improved variable hysteresis-band current-control in natural frame for a three-phase shunt active power filter. The proposed control algorithm is based on three decoupled sliding-mode controllers ...
  • Control strategy to maximize the power capability of PV three-phase inverters during voltage sags 

    Sosa, Jorge Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Matas Alcalá, José; Al-Turki, Y.A. (2016-04-01)
    Article
    Open Access
    Under voltage sags, grid-tied photovoltaic inverters should remain connected to the grid according to low-voltage ride-through requirements. During such perturbations, it is interesting to exploit completely the distributed ...
