    摘要: 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. Each of the fusible elements are operative to open-circuit when an electrical device coupled thereto causes an electrical current to flow through the fusible element in excess of a current rating of the fusible element.

    摘要: 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. Therefore, when current flows into the dot end of one of the windings (68) and (70) and out of the dot end of the other winding, the net flux induced in the magnetic structure (44) is zero. A primary winding (62) is wound about the second leg and induces a flux into the magnetic structure (44).
