Power Factor Correction, TI-SEPIC – DCM, BLDC, Total Harmonic Distortion.


Power Factor Correction (PFC) is one of the research areas in the field of power electronics due to the enormous power required in various industrial applications. In this work, a SEPIC converter with the Tapped Inductor model which is operated in Discontinuous current Conduction Mode (TI-SEPIC- DCM) is proposed for a BLDC Drive. The proposed TI-SEPIC-DCM also improves the voltage gain with the help of voltage multiplier cell and charge pump circuit. It also helps in attaining the ZVS and ZCS, which results in higher switching frequency range and reduction in size reduction. Moreover, a third order harmonic reduction control loop is also proposed to attain a better third order harmonic elimination. The proposed work has been simulated using MATLAB simulink and the results are also validated.
