FIELD: electricity.SUBSTANCE: AC-to-DC voltage transducer comprises a three-phase transformer, primary phase windings of which are connected each with an extreme identical lead to the common lead of back-to-back parallel main controlled valves, the other common lead of which is connected to the appropriate phase input lead, with an intermediate lead - to the common lead of back-to-back parallel connected additional controlled valves, the other common lead of which is connected to a zero input lead, and secondary phase windings jointly with valves, number of which is multiple to six, are connected in accordance with the rectifier circuit, free extreme leads of primary phase windings are connected to each other, besides, the intermediate lead divides the number of turns of the primary phase winding at the ratio ofwhere: w- number of turns between the intermediate and extreme lead of the primary phase winding, w- number of turns between its intermediate and free extreme lead.EFFECT: increased usage of primary transformer windings by voltage.4 cl, 4 dwg |
