Regulator Strategies for Switched Reluctance Generators Based on Direct Energy Control

The causes of voltage ripples in switched reluctance generator (SRG) are analyzed. At first, on the foundation of the driving circuit with a three-level topology, the energy conversion relations in different rotator positions or in different electric level states was set up. Secondly, the SRG outputting voltage was controlled by a new method named direct energy control. Then, the hysteresis control logic of the direct energy control was designed. At last, we conduct the simulation experiments. The simulation results show that this method can effectively decrease the output voltage ripples of SRG.
