一种基于Cuk变换器的无刷直流电机换相转矩脉动抑制新方法

In this paper, 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 commutat...
