ABSTRACT:
A three-phase choke, includes a five-leg core formed of a central core leg carrying a winding, two outer core legs each carrying a winding and two return legs, the central and outer core legs being formed of stacks of laminations, a lower yoke having ends adjacent the return legs, an upper yoke formed of sections having ends defining gaps between the ends of the sections and gaps between the return legs and the ends of the sections of the upper yoke adjacent thereto, and non-magnetic material filling the gaps, the yokes and return legs having cross sections being smaller than the cross sections of the core legs carrying a winding, each of the return legs and the ends of the yokes adjacent thereto having a first magnetic resistance, the upper yoke having a respective portion thereof disposed between the central core leg and each of the outer core legs each having a second magnetic resistance, and the lower yoke having a respective portion thereof disposed between the central core leg and each of the outer core legs each having a third magnetic resistance, the magnetic resistances being substantially determined by the thickness of the gaps, and the sum of one of the second and one of the third magnetic resistances being greater than one of the first magnetic resistances.
