This paper presents a 3-phase 4-leg 4-wire voltage sag compensator based on three dimensional space vector modulation in abc coordinates which can handle a neutral current under voltage sag and nonlinear load conditions. The topology of this hardware consists of a voltage sag detector, a DC/DC conve...
