In this paper, a newly developed 15KVA non-brush D.C. engine with revolving rectifier is introduced. The principle and topology of the engine are discussed and analyzed in detail. Moreover the major points in parameter design, method of realization, the experimental result of the prototype and the Saber simulation wave are presented. The results show that this system has a high-efficiency, high-power factor, small size, low-weight and good electrical property, and it can operate continuously for a long time with no need for maintenance. This engine may find a promising prospect of application in the manufacture of unmanned airplanes.
