Abstract: The switched reluctance generation（SRG） mode is widely used in doubly salient electro-magnetic generators.In this paper,an optimized topology of SRG was proposed.Firstly,the magnetic energy relationship of the double salient generator was analyzed.According to the analysis,an optimized topology that is the Boost Half-wave Rectifier（BHR） was proposed.With the help of Finite Element Analysis（FEA）,the performance of the BHR and SRG generation mode were compared,for a 12/8 poles doubly salient electro-magnetic generator.Based on that simulation,the factors that affect the armature currents were analyzed when the generator is under different loads.Experimentation of a prototype verified the correctness of the FEA analysis.Analysis results show that the maximum power of the doubly salient generator is improved significantly when it use the new generation topology of BHR compared to the traditional power generation mode of SRG.
