This paper discusses the configuration and operating principles of a novel Rare-Earth Permanent Magnet (REPM) brushless DC generator which achieves the optimum combination of square waveform REPM AC generator and boost type power converter. It also studies in detail the performamce characteristics of this system;the relationship among output volt-age U0 ,duty cycle Dy ,AC input current It and machine speed n ;the DC output ripple △U0, input current ripple △Ii , load connection characteristics and efficiency. An experimental system has verified the analysis method and results of this paper.The advance of power devices will make this new DC generator robust and durable. Because our country abounds in REPM material,there will be a hight prospect for the develop ment of REPM machines. On the other hand,the development of this type of machines will greatly depend up that of the power converters. This paper deals with this problem in both aspects and provides the theoretical and technical bases for the development of such machines.
