Regulator Strategies for SRG Based on Direct Energy Control

分析引起开关磁阻发电机(SRG)电压脉动的原因,在三电平拓扑结构驱动电路的基础上,研究不同转子位置和电平状态下的能量转换关系,采用直接能量控制的方法对SRG输出电压进行控制,设计直接能量控制的滞环控制逻辑,并进行仿真实验。仿真结果证实该方法可以有效地减小SRG的输出电压脉动。

This paper analyzed the causes of voltage ripples in switched reluctance generator （SRG）. On the foundation of the driving circuit with a three-level topology, studied the energy conversion relations in different rotator positions or in different electric level states. By adopting direct energy controlling method, can control the SRG outputting voltage, and design hysteresis control logic of the direct energy control, thus conduct the simulation experiments. The simulation results verified that this method could effectively decrease the output voltage ripples of SRG.
