脉冲发电机因为其同等功率下体积较小、储能密度高、脉冲运行对电网压力小等优势在大功率的脉冲应用场景中具有非常大的优势。与现在通常使用的同步脉冲发电机、直流脉冲发电机或者同步发电机进一步改进的补偿脉冲发电机（CPA）等脉冲源相比，开关磁阻脉冲发电机（SRPG）结构更加简单坚固、过载能力强且具有天然的脉冲发电特性，十分适合机载、舰载情况下的脉冲技术应用。本项目率先进行针对开关磁阻电机在脉冲功率领域中应用的基础研究；探索解决SRPG系统产生重复脉冲的功率拓扑结构设计问题，提出优化后的SRPG功率拓扑结构；建立基于脉冲输出的SRPG控制系统；开展脉冲波形控制以及窄脉冲成形技术的研究、从实际应用角度分析不同负载状态下SRPG重复频率脉冲的负载特性；建立SRPG非线性数学模型以及SRPG的供电数学模型；针对SRPG的电路寄生参数特点进行寄生参数提取方法以及寄生参数对系统影响的研究；建立实验样机与负载测试平台验证相关理论分析的正确性。项目培养毕业博士4人、毕业硕士研究生9名，博士后1人。在国内电气工程专业核心刊物和期刊17篇（含录用）以上。国际会议上发表论文会议9篇，8人次参加线上线下国际学术交流会议，申请授权发明专利9项。获省级科技奖2项。
