Comparative Analysis of CUK, SEPIC, Buck-Boost and ZETA Converters to Reduce Commutation Torque Ripple in BLDC Motor

Abstract

The projected torque ripple minimization of BLDC motor is implemented in the working platform having configurations of windows 10, Intel (R) Core i7 processor, 2.2 GHz, 8 GB RAM, and the parameters are analyzed in the MATLAB Simulink toolbox. BLDCM system is analyzed with different converters such as SEPIC, Buck Boost, CUK and Zeta converters to accomplish the reduced commutation torque ripples over the low speed drives. Also, obtained the desired voltage much faster and reduce torque ripple with high efficiently at very low speed. The model of BLDC motor with different converter circuit is simulated and its results are interlinked and displayed in PC through Internet of Things.
