The invention relates to a prism-type connexion applied to two-phase and three-phase converters, but can be extended from two to six phases, prism connections ETO-120-2/3 (fig.6a) being used as a reference which indicate that the missing phase is formed from two supply phases in fig 6(a), i.e. phase a by sections a1 and a2, phase b by sections b1 and b2, phase c by sections c1 and c2, 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 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 t o obtain a balanced three-phase system with neutral that can connect any three-phase, two-phase or single-phase load from a two-phase supply with two wires, thereby rendering the invention remarkable in relation to existing electrical converters which have no general application. Moreover, said prism-type connection or system may be applied to engines and generators, thereby having unlimited applications. |
