Abstract
Aiming at the impulse of the DC bus voltage of the switched reluctance motor under high speed condition, as well as the problem of insufficient power shortage in the medium and low speed state, the regenerative braking process of the switched reluctance motor is analyzed. In low-speed state, the position angle combined with full voltage shut down method, in high-speed state, the angular position with zero voltage keep opening in three step control method, solve the impact of switched reluctance motor in high speed of regenerative braking of DC bus in a certain extent, and the low status of power shortage problem is proposed in this paper.
