Abstract: A fault current limiter is provided that comprises a magnetically saturable core. The first core includes a first leg, a second leg, with a first AC coil wound on the second leg, a third leg, with a second AC coil wound around the third leg, the first and second AC coils being wound in series and connected to a first phase AC source, and a fourth leg. The first magnetic biasing unit is arranged to produce a first closed magnetic circuit in the first leg and the second leg that has a first flux direction, and the second coil is arranged to produce a second closed magnetic circuit in the fourth leg and the third leg that has a second flux direction, wherein the first flux direction opposes the second flux direction. The first and second AC coils are arranged to produce a first closed AC magnetic circuit in the second and third legs in an AC flux direction that alternates with each AC half-cycle.
