Abstract
A device includes a three phase supply input including a first phase input, a second phase input, and a third phase input. The device further includes a three phase supply output including a first phase output, a second phase output, and a third phase output. The device further includes a three-phase wye-connected auto-transformer having windings including a first winding, a second winding, and a third winding. At least one of the windings is rated for at least a maximum line to line voltage of the three phase supply input. The other two windings are rated for at least a maximum line to neutral voltage of the three phase supply input. One or more of the windings of the three-phase wye-connected auto-transformer are configured to be tapped to generate a voltage sag output as the three phase supply output.
