摘要： There are provided: a main three-phase full-wave rectifier (8) that converts three-phase AC (R phase, S phase, T phase) into DC; a transformer (9) that outputs AC of a total of six phases corresponding to the points that equally divide by three the arcs drawn in a transformer vector diagram in which an equilateral triangle is formed whereof the R phase, S phase and T phase are vertices, centered on each vertex and linking the remaining two points; and two auxiliary three-phase full-wave rectifiers (12) and (13) in that convert into DC the six-phase AC that is output from the transformer (9), the output lines of the main three-phase full-wave rectifier (8) and two auxiliary three-phase full-wave rectifiers (12) and (13) being connected in parallel. The current flowing in the DC line through the transformer can therefore be reduced to ⅓ of the whole in the case of an 18-pulse rectifier, so enabling the capacity of the transformer to be reduced.
