COMPARISON BETWEEN INTERLEAVED BOOST CONVERTER BASED 6-SWITCH AND 4-SWITCH VSI FED PMBLDC MOTOR DRIVE

摘要

In this paper, an improved interleaved boost converter topology for PMBLDC Motor has been proposed. The proposed interleaved boost converter topology has been used for 6-switch and 4-switch VSI fed PMBLDC motor drive and details are presented. The proposed research work has been implemented under Matlab/Simulink environment and tested for different operating conditions. The performance of 4-switch VSI fed PMBLDC motor drive compared with the performances of 6-switch VSI fed PMBLDC motor. From the results, it is observed that 4-switch VSI fed PMBLDC motor performance is superior to 6-switch VSI fed drive in certain aspects. In some other aspects performance of 6-switch VSI fed drive is superior to 4-switch VSI fed drive. Merits and demerits of each one of the schemes are investigated thoroughly under different operating conditions and corresponding results are presented.
