Torque ripple in Brushless dc motors is generally undesirable. Torque ripple causes increased acoustic noise and undesirable speed ripple preventing BLDC motor from achieving high performance. This article presents the method of reducing torque ripple in BLDC motor. This study presents an approach to reduce torque ripples by controlling the voltage while maintaining speed. To get the desired dc link voltage, a singleended primary inductor converter (SEPIC) circuit is used to control the input of the commutation circuit.

W artykule analizuje się możliwości minimalizacji zafalowań momentu napędowego w silniku bezszczotkowym. Zmniejszenie tętnień uzyskuje się przez sterowanie napięcia utrzymującego prędkość. W celu utrzymania pożądanego napięcia dc wykorzystano niesymetryczny przekształtnik typu DSEPIC.
