The theme of this thesis is to improve the torque ripple suppression and regenerative braking of the SRM Several torque ripple reduction methods are surveyed including torque sharing function (TSF) direct torque control (DTC) and direct instantaneous control (DITC) Based on direct torque control (DTC) this thesis introduces constant frequency modulator with fuzzy logic to further reduce torque ripple and maintain fixed operating frequency A 3kW SRM and an asymmetric half bridge converter are used to verify the effectiveness of the proposed strategy Besides this thesis also addresses regenerative braking mode of the SRM by current hybrid chopping Fuzzy logic is applied to the current controller to suppress current spikes when the SRM operates in high current condition (saturated region)
