A ground power unit for providing do power for aircraft includes a source of 3-phase ac power and a transformer/rectifier arrangement for converting 3- phase ac power to do power. The transformer/rectifier arrangement includes an A-phase transformer formed by an A-phase magnetic member, an A-phase primary winding having first and second sides, and an A-phase secondary winding; a B-phase transformer formed by a B-phase magnetic member, a B-phase primary winding having first and second sides, and a B-phase secondary winding; and a C-phase transformer formed by a C-phase magnetic member, a C- phase primary winding having first and second sides, and a C-phase secondary winding. The A-phase primary winding first side is connected to receive A-phase power, the B-phase primary winding first side is connected to receive B-phase power, and the C-phase primary winding first side is connected to receive C-phase power. The A-phase primary winding second side, B-phase primary winding second side and C-phase primary winding second side are connected together for delivering current traveling out of one of the second- sides into at least one of the other second sides.
