Abstract: An apparatus for providing independent over-current protection to a plurality of electrical devices and a transient-voltage suppression system employing the apparatus. In one embodiment, the apparatus includes a non-conductive body having a plurality of bores extending through the body from a first portion to a second portion of the body, a plurality of fusible elements corresponding to and disposed within the plurality of bores, each of the fusible elements having a first terminal proximate to the first portion of the body and a second terminal proximate to the second portion, and a common electrode coupled to the first terminal of each of the plurality of fusible elements. The common electrode is couplable to a source of electrical power and the second terminals of each of the plurality of fusible elements are couplable to an electrical device, such as a metal oxide varistor in a transient-voltage suppression system.

Abstract: An integrated magnetic filter inductor having series and common mode windings includes a magnetic core (44) having a first leg (46), a second leg (48), and a third leg (50). The first leg (46) is connected to the second leg (48) with bridging structures (52) and (54). In a similar manner, the third leg (50) is connected to the second leg (48) with bridging structures (56) and (58). A common mode winding (64) is wound about the bridging structure (52) with a given dot orientation. A common mode winding (66) is wound about the other bridging structure (54) with the same dot polarity. Current flowing into the dot terminal of the common mode winding (64) and out of the dot terminal of the common mode winding (66) result in a net zero magnetic flux induced in the magnetic structure (44). A common mode winding (68) is wound about the bridging structure (56) with a predetermined dot polarity. A common mode winding (70) is wound about the other bridging structure (58) with the same dot polarity.

Abstract: A core for an integrated magnetic power converter includes a continuous magnetic structure having first and second legs and a magnetic flux conducting path therebetween. A primary winding is disposed on the first leg. A first secondary winding is disposed on the first leg. A second secondary winding is disposed on the second leg. The first leg has a cross-sectional area which is greater than the cross-sectional area of the second leg.
