Abstract: 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.
