TRANSFORMER/RECTIFIER FOR AIRCRAFT GROUND POWER UNIT

摘要

A ground power unit for providing do power for aircraft includes a source of3-phase ac power and a transformer/rectifier arrangement for converting 3-phase ac power todo power. The transformer/rectifier arrangement includes an A-phasetransformer formed byan A-phase magnetic member, an A-phase primary winding having first and secondsides,and an A-phase secondary winding; a B-phase transformer formed by a B-phasemagneticmember, a B-phase primary winding having first and second sides, and a B-phasesecondarywinding; and a C-phase transformer formed by a C-phase magnetic member, a C-phaseprimary winding having first and second sides, and a C-phase secondarywinding. TheA-phase primary winding first side is connected to receive A-phase power, theB-phase primarywinding first side is connected to receive B-phase power, and the C-phaseprimary windingfirst side is connected to receive C-phase power. The A-phase primary windingsecond side,B-phase primary winding second side and C-phase primary winding second sideareconnected together for delivering current traveling out of one of the second-sides into at leastone of the other second sides.
