In this paper, a detailed analysis on torque ripples of brushless dc drives in both commutation and conduction region is given. A new control strategy for the elimination of torque ripples in BLDC motor by employing PWM-ON -PWM scheme has been introduced. PWM-ON-PWM strategy is mainly applied to compensate the commutation torque ripples during commutation ...

In this paper, an efficient technique for implementation of soft-error tolerant shift registers is presented. The proposed paper uses two implementations of the basic registers with different structures operating in parallel. A soft-error occurring in either shift registers causes the outputs of the shift registers to differ, or mismatch, for at least one sample. The ...
