This paper presents an original study on the generated torque ripples of phase
commutation in the Four-Switch, Three-Phase Inverter (FSTPI) Brushless DC (BLDC)
motor drive which is suitable for low cost applications. Analytic values of torque ripple and
commutation duration are obtained for different operation conditions. Moreover, limitation
on the speed range operation caused from splitting of the DC-link voltage is shown exactly.
Then a novel current control technique is developed to minimize the commutation torque
ripple for a wide speed range. The technique proposed here is based on a strategy that the
current slopes of the rising and the decaying phases during the commutation intervals can
be equalized by proper duty-ratios at commutations. Finally, the validity of the proposed
analysis and developed torque ripple reduction technique are verified via simulation.
