Abstract In order to improve the output performance of switched reluctance generator (SRG) system, an improved separately-excited converter for SRG is proposed in this paper to improve the output voltage and power in DC power generation application. An auxiliary circuit is inserted into the front end of the converter and integrated into the conventional asymmetrical bridge separately excited converter. By controlling the auxiliary switch in the auxiliary circuit, the excitation voltage and generation voltage can be increased, and the excitation and demagnetization process can be accelerated, thereby improving the power generation performance of SRG system. This paper analyzes the working mode of the improved separately excited converter, compares and simulates the different power generation performance of the improved converter and the conventional converter, and studies the influence of the conduction angle of the main switch and the auxiliary switch, the size of the auxiliary capacitance and the load capacitance on the performance of the power generation system. Finally, the power circuit of the improved converter is fabricated, and the experimental platform based on dSPACE is built. The simulation and experimental results show that the improved converter can significantly improve the generation voltage and power of the SRG system. The experimental results verify the correctness of the theoretical analysis and the effectiveness of the proposed improved separately excited converter.
