This project is mainly based on Cuk converter, a novel commutation torque ripple reduction strategy is proposed for the brushless DC motor. Output modes (buck–boost mode and boost mode) of the Cuk converter during the commutation period and normal conduction period are altered by designing a mode selection circuit, which can reduce commutation torque ripple over the entire speed range. During the commutation period, Cuk converter operates in the boost mode to step up the input voltage of three-phase bridge inverter and then meet the voltage demand of commutation period, such that the commutation torque ripple can be reduced by keeping the non commutated current steady.
