SEPIC Based PFC Converter for PMBLDCM Drive in Air Conditioning SystemKeywords: PFC converter , SEPIC , PMBLDC motor , air - c onditioning , po w e r quality (PQ) Abstract: Inthispaper,Apowerfactorcorrection(PFC)basedsingleendedprimaryinductor converter(SEPIC)isusedtoregulateDCbusvoltageof voltagesourceinverter(VSI)torunPMBLDC motor. PermanentmagnetbrushlessDC motor(PMBLDCM)isusedinair-conditioning systems and runsatrated torque andvariablespeed to achieveenergyconservation.Theanalysis,designandperformanceoftheproposedPFCconverteriscarriedoutfora1.2kW,1200rpm,164 V PMBLDCMused in air-conditioningsystem.ThePFCconverterismodeledand itsperformanceissimulatedinMatlab-Simulinkenvironment.Theimprovedpower factorofthedriveis evaluated inwide range.
