چکیده
This paper proposes a torque ripple reduction for brushless DC (BLDC) permanent magnetic (PM) motor drive based on the DC-link voltage pulse amplitude modulation (PAM). The proposed method improves drawback BLDC drives at low speed. have better inverter efficiency and requires position sensing resolution. However, both freewheeling current during diode conduction discontinuous phase cause high ripples. In this paper, front-end converter is added to improve Although integration of has been reported, regulation compensation novelty. On basis, bus modulated manipulate dynamically every commutation period. addition considering six-step commutation, also regulated with 6th-order spatial harmonic minimize reflected ripple. verified by simulation different PM types. According experimental results, around 40% demonstrated using modulation.
