Abstract:
A rectifier, comprising:a main three-phase full-wave rectifier that converts three-phase AC, phase, S phase, T phase into DC; a transformer that outputs AC of a total of 3(nâˆ’1) phases corresponding to the points that equally divide by n=2, 3, the arcs drawn in a transformer vector diagram in which an equilateral triangle is formed whereof said R phase, S phase and T phase are vertices, centered on each vertex and linking the remaining two points; and a plurality of (nâˆ’1) auxiliary three-phase full-wave rectifiers that convert into DC the 3(nâˆ’1) phase AC that is output from said transformer, wherein output lines of said main three-phase full-wave rectifier and said 3(nâˆ’1) auxiliary three-phase full-wave rectifiers are connected in parallel.
