Sepic converter fed permanent magnet brushless dc motor drive

Abstract

A unique single-stage bridgeless single-ended primaryinductor converter (SEPIC) architecture is developed in this study to newlineprovide substantial power component adjustment whilst operating newlineBrushless Direct Current (BLDC) motor. The increased use of electrical newlineparts has prompted improvements in the power factor of alternating newlinecurrent (AC) circuits. The use of Power Factor Correction (PFC) in newlinepower-electronics investigation and the designing of PFC converter has newlinesignificantly aided in the reduction of frequency deviation in transmission newlinelines and the improvement of transmission efficiency. newlineIn the ancient times, buck, buck-boost and boost-type PFC newlineconverters, and traditional SEPICs contributed in increasing the power newlinecomponent. However, the need to improve system reliability when using newlinefewer parts has resulted in the development of unique bridgeless SEPICs. newlinePermanent Magnet Brushless Direct Current (PMBLDC) motors are newlinewidely employed in industrial and home uses due to its significant newlinedependability and extended lifespan. In comparison to brushed DC newlinemotors, they have a lower inertia, greater productivity, superior power newlinedensity, a larger operating speed, greater torque, and improved heat newlinedissipation. newlineIn the first stage of the research, a novel bridgeless AC-DC newlineSEPIC for PFC is suggested. The suggested single-phase rectifier has two newlinebidirectional switches (MOSFET) newline
