The invention relates to a prism-type electrical converter for the generation, transmission, distribution and supply of electric current, which essentially comprises two systems, namely a magnetic system and an electrical system, plus an additional thermal control or cooling system. As a result, the converter has three-phase side. The three-phase magnetic circuit forms the base of the magnetic circuit. The two-phase side is formed on the three constituent magnetic circuits thereof. More specifically, the inventive converter comprises a magnetic silicon steel core which can take the form of broken or continuous spiral columns, having a circular, elliptical, cross-shaped section, etc., an Evans-type converter which is a broken spiral-type converter or a Wescord-type converter or coiled with junction. The operation of the inventive converter is based on the most commonly used system, comprising the vectorial sum of the two existing phases, such as to produce the third phase, but can be extended from two to six phases. Prism connections ETO- 120 - 2/3 and ETO- 240 - 2/3 are used as a reference, which indicate that the missing phase is formed from two supply phases, i.e. phase a by sections a 1 and a 2, phase b by sections b 1 and b 2, phase c by sections c 1 and c 2, in which any phase can be generated depending on the supply phases. Therefore, if phases a and b are present, the missing phase is c, if phases b and c are present, the missing phase is a, and if phases a and c are present, the missing phase is b, such as to produce the phase that does not already exist. In this way, a three-phase output system with any voltage level supplies the three-phase voltage which, by means of another output system with any voltage level, supplies the three-phase voltage that can be used for any electrical system that is used to generate, transmit, distribute and supply electrical power. In addition, the prism conversion system can be used to obtain a balanced three-phases system with neutral that can connect any three-phase, two-phase or single-phase load from a two-phase supply with two wires, there by rendering the invention remarkable in relation to existing electrical converters which have no general application. Moreover, said prism-type connection or system has unlimited applications. Furthermore, the electrical converter is produced in a novel manner comprising the following steps consisting in: producing the magnetic core, stacking to form a three-phase assembly, forming packets, pressing same to form the power or distribution power, forming the definitive magnetic core and, finally, annealing said magnetic core, thereby defining a novel method of producing the inventive prism-type converter.
