PROBLEM TO BE SOLVED: To simplify wiring inside a twelve-phase rectifier circuit by omitting a DC reactor in the twelve-phase rectifier circuit. SOLUTION: A twelve-phase rectifier circuit 1 has a three-phase bridge rectifier circuit A21, which rectifies an output voltage of a winding 13 of three-phase Y-connection of a transformer 11, and a three-phase bridge rectifier circuit B22 for rectifying an output voltage of a winding 14 of three-phase delta-connection. The output side of the three-phase bridge rectifier circuit A21 and the output side of the three-phase bridge rectifier circuit B22 are connected in parallel. Each phase on the primary input side of the transformer 11 is provided with AC reactors 2U, 2V, and 2W. COPYRIGHT: (C)2009,JPO&INPIT
