Abstract:
Improved modular transient voltage surge suppressor apparatus are disclosed that equalize transient current sharing between multiple modules. In general, such apparatus includes first and second transient voltage surge suppression modules, each module having a non-conductive housing with a surge suppression circuit contained therein, and first and second electrically-conductive buses mechanically coupled to the non-conductive housing and electrically coupled to first and second terminals of the surge suppression circuit, respectively. A first bus coupler couples the first electrically-conductive buses of the first and second transient voltage surge suppression modules and a second bus coupler couples the second electrically-conductive buses of the first and second transient voltage surge suppression modules, whereby the surge suppression circuits in each of the first and second modules are electrically coupled in parallel. A first electrical conductor coupler is electrically coupled to, and physically located proximate, the first electrically-conductive bus of the first transient voltage surge suppression module, and a second electrical conductor coupler is electrically coupled to, and physically located proximate, the second electrically-conductive bus of the second transient voltage surge suppression module, whereby the electrical path length from the first electrical conductor coupler to the second electrical conductor coupler and through the surge suppression circuit of the first transient voltage surge suppression module is substantially equal to the electrical path length from the first electrical conductor coupler to the second electrical conductor coupler and through the surge suppression circuit of the second transient voltage surge suppression module.

Abstract:
Improved modular transient voltage surge suppressor that can reduce, or eliminate, the possibility of failures due to electrical-arcing are disclosed. In general, such transient voltage surge suppressors include: a non-conductive body having a first internal chamber and a second internal chamber separated by an internal wall structure, the interior region of the first internal chamber being substantially isolated from the interior region of the second internal chamber; a first electrical conductor extending through an external wall of the body and into the first internal chamber; a second electrical conductor extending through the external wall of the body and into the second internal chamber; fuse element(s) disposed within the first internal chamber, the fuse element(s) having a first terminal coupled to the first electrical conductor and a second terminal; transient suppression element(s) disposed within the second internal chamber, the transient suppression element(s) having a first terminal coupled to the second electrical conductor and a second terminal; and electrically-conductive means for coupling the second terminal of the fuse element(s) to a second terminal of the transient suppression element(s) whereby the fuse element(s) and the transient suppression element(s) are coupled in series between the first electrical conductor and the second electrical conductor, the means for coupling extending through the internal wall structure intermediate to the first internal chamber and the second internal chamber, whereby the fuse element(s) is (are) substantially isolated from the transient suppression element(s).

Abstract:
Improved modular transient voltage surge suppressor apparatus having interconnecting status interfaces between adjacent stacked modules are disclosed. In general, such apparatus include first and second transient voltage surge suppression modules, the first and second transient voltage surge suppression modules being adapted to be interchangeably coupled in a stack. Each of the first and second transient voltage surge suppression modules include a non-conductive housing having a surge suppression circuit contained therein, wherein the non-conductive housing has a top surface and a bottom surface; status monitoring circuitry coupled to the surge suppression circuit, wherein the status monitoring circuitry includes at least a first status terminal and a second status terminal; and upper and lower status ports, the upper status port being proximate the top surface of the non-conductive housing and providing access to the first status terminal and the lower status port being proximate the bottom surface of the non-conductive housing and providing access to the second status terminal. The first status terminal associated with the upper status port of the first transient voltage surge suppression module is coupled to the second status terminal associated with the lower status port of the second transient voltage surge suppression module when the second transient voltage surge suppression module is stacked on top of the first transient voltage surge suppression module (or vice versa), thereby allowing the status monitoring circuitry associated with the first and second transient voltage surge suppression modules to be directly interconnected.

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. 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.
Integrated Magnetic Inductor Having Series And Common Mode Windings
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.
