SEPIC-based Harmonic Distortion Reduction in BLDC Motors
Main Article Content
Abstract
— This study examines a novel drive method for
BLDC motor speed regulation. In this mode, the line voltage
waveform is observed while having both voltage and current.
This allows us to deduce harmonics of lower order and,
possibly, increase the cosine angle of voltage and current when
neither voltage nor current sensor equipment is present. For
driving a permanent magnet brushless dc (BLDC) motor with
unipolar currents, a front-end SEPIC and a switch are proposed
in series with each phase. One benefit of using lower voltage
applications is that the supply voltage can be obtained for better
current regulation. The SEPIC converter is built to work with
an ac supply in the irregular conduction mode. The present
topology is simulated and verified by using
MATLAB/SIMULINK
