SU17499A1 - Solid contact rectifier - Google Patents

Description

It is known that solid contact rectifiers consisting of several layers of different materials produce a particularly high return of rectified current if one or more of these layers are made of copper oxide or saturated mixtures of copper oxide (CuJ. Compared to the known copper oxygen compounds, the unsaturated copper halide compounds are much more conductive, which makes them particularly applicable to dry rectifiers.

It is possible to prepare such an ‑ solvent using copper iodide, for example in such a way that a copper iodide plate is placed on one copper plate serving as a single electrode, above which some suitable compound, for example, an oxide, a sulfur compound or the like. p. and then the metal plate as the second electrode. It is advantageous to combine both of these plates or slr into one body, obtaining a chemical compound on the inlet plate, HaffpHMep, a silver plate.

lead or the like is supplied with a layer of silver iodide (-Ld) or lead iodide (Pb / L). These iodide compounds present on a silver or lead plate have electrolytic conductivity. Similarly, in the manufacture of a plate of copper iodide, it can be simultaneously combined with on the current input of a copper plate. If with such an arrangement of the plates (for example; a copper feed plate, next, then a plate, copper iodine or a layer of copper iodide and, finally, a plate of silver iodide or

lead iodide) copper, and along with it iodide; copper forms a positive electrode, and a plate of silver iodide or lead iodide is a negative electrode, then the resistance of the whole device is much less than in the opposite case, when copper, and therefore copper iodide, form negative

than in the opposite direction. This property can be used to rectify the current. The latter occurs at the point of contact between copper iodide and a metal coated with an electrolytically conductive compound, such as silver or lead, while the current in place at the place of copper iodine copper is the same in both directions. This proposed rectifier differs from the already known copper oxide rectifier ((.-, 0), in which the current is rectified between copper and its oxide, and the type of metal that serves as a current feed to the oxide layer, in this case is only of secondary importance.

A solid contact rectifier, therefore, is arranged as follows: a two-layer plate consisting of copper and copper iodide is pressed from the side of copper iodide to a silver plate covered with a thin layer of silver iodide or to a lead plate covered with a layer of lead iodide.

I If necessary, all four layers j can be joined together in one I plate. Extreme layers of the product: thus, the rectifier serves to supply and divert the current.

For strength straightener, copper iodide should contain a small amount of free iodine.
