摘　　要：分析了开关磁阻发电机(SRG)的发电运行条件和提高输出功率的关键因素,提出用三电平功率变换器加入一个中间惯性状态,增大励磁电流和发电续流区的平均电流,以提高SRG的输出功率;采用SRG电压反馈控制系统,保证同时获得良好的恒定输出电压品质;提出三电平功率变换器的开关控制策略,建立基于自励发电模式和电流斩波控制模式的SRG电压反馈控制系统仿真模型;仿真研究验证了该方法的可行性和有效性。The operation conditions and the key factors to enhance the output power of switched reluctance generators （SRG） were analyzed. The method of using an intermediate freewheeling by three-level power converter to improve the output power of SRG was proposed, boosting the magnetizing current and the average current of generation flow region. The voltage feedback control was used to ensure a good constant output voltage quality. The switching control strategy of three-level power converter was introduced. The SRG voltage feedback control system model based on self-excitation pattern and current chopper control was established. Simulation study verified the feasibility and efficient of the method.
