Abstract:
The speed – torque features with smooth operation of permanent magnet Brushless DC Motor (PMBLDC) drives have received their recent attention in industries. The working functionality of diode bridge rectifier in PMBLDC motor drives are primarily being a cause for the reduction of power factor which in-turn makes depression in the quality of the power generated. To control the above problem, a single switch modified SEPIC-Single Ended Primary Inductor Convertor with Power Factor Correction (PFC) can be used at the input end. The commutation torque ripples can be effectively managed using modified SEPIC convertor. The safety of the drive is also efficiently addressed due to the production of buck-boost efficiency. The simulation analysis shows power quality and power factor in an improved manner challenging the state of art techniques.
