Abstract The reason for the output voltage ripple of the switched reluctance generator (SRG) is analyzed. In order to solve the problem of slow voltage build-up and ripple in SRG output voltage under the traditional PI control mode, a control strategy for variable opening angle and fuzzy and PI parallel control is proposed (variable open angle F-PI parallel control strategy). When the SRG starts working, the output voltage is quickly established by changing the opening angle, fuzzy PWM and PI current chopping control are realized by the error of the given voltage and output voltage and the rate of change of the error. The non-linear model of SRG were established by Matlab/Simulink and simulation analysis were conducted. Finally, based on the experimental platform, the experimental analysis of the variable open angle F-PI parallel control strategy and the traditional PI control strategy were carried out. The experimental results show that the F-PI parallel control strategy based on variable opening angle can quickly establish the generator voltage. When the speed or load changes, the output voltage can quickly follow the given value, and effectively reduce the output voltage pulsation, thereby improving the quality of power generation.

Key words： Switched reluctance generator (SRG) voltage ripple change the opening angle fuzzy PWM PI control
