This paper proposes and implements a new topology of hybrid excitation doubly salient brushless DC generator. Configuration and flux control principle of the generator are presented. Two-dimensional finite element methods are used to investigate the static field distribution characteristics of this new type of generator. Field-circuit coupled analysis is successfully performed, and the output characteristics of different windings are obtained. A prototype hybrid excitation doubly salient brushless DC generator is designed and developed, and the experimentation is also given to verify the validity of the proposed brushless DC generator with one and dual terminal outputs. The results confirm the excellent field-regulation capability of hybrid excitation doubly salient brushless DC generator, and the rectified output of permanent magnet part can serve as the independent power of the excitation winding when the hybrid excitation doubly salient brushless DC generator has two sets of output windings.
