“…Hence, it can achieve low manufacturing cost, low copper consumption and highpower generation efficiency. In addition, the stators and rotors of SRG systems are controlled synchronously, and the stability of system can also be guaranteed even when the operating frequency is low [4]- [7]. However, the existence of large output voltage ripples degrades the power generation performance.…”

The Switched Reluctance generator (SRG) has been widely used as a constant voltage source due to its advantages of simple structure, low cost and high control flexibility. However, the output voltage ripples cannot be ignored due to its unique operating principle with phase commutation. In this paper, the influence of the control parameters on the output voltage ripples are analyzed, and a fly-wheeling pulse train (FW-PT) control strategy is proposed to suppress the voltage ripple. The output voltage can be regulated by the FW-PT control strategy by using two or more sets of preset control pulse combinations, therefore it has the advantages of simple circuit implementation, no Network compensation and fast response speed. The characteristics of steady-state and dynamic behaviors of the switched reluctance power generation system by using different control strategies are simulated and compared, and a platform of 200W 8/6 SRG is built for experimental verification. Simulation and experimental results confirm that compared with the traditional PID control strategy, the FW-PT control strategy can be used to not only suppress the output voltage ripple, but also achieve faster response and dynamic characteristics.INDEX TERMS SR power generation system, pulse train, fly-wheeling current, voltage ripple, dynamic characteristics.
