This paper presents a power control method of high-speed single-phase BLDC motor. Most electricappliancesrequireapowerfactorcorrector(PFC)tomitigategridcurrentharmonics.However,thereactivecomponentsandpowersemiconductorsinthePFCincreasesystemcostanddimension.Inthispaper,anewmotordrivesystemforahigh-speedsingle-phaseBLDCmotorisproposed,whichcandecreasegridcurrentharmonics without PFC by directly manipulating motor power and eliminating bulky electrolytic dc-linkcapacitor.Giventhattheproposedmotorpowercontrolmethoddoesnotrequiremotorcurrentcontroller,nocurrentsensorisnecessary.Moreover,theproposedalgorithmscanbeeasilyimplementedusingalow-costmicro-controller.Theeffectivenessoftheproposedpowercontrolmethodisverifiedbyexperiments.Keywords:Single-phaseBLDCmotor,Powerfactorcorrector,High-speedmotor,Gridcurrentharmonics,Powercontrol,Fanmotor Papernumber:TKPE-2016-21-2-7PrintISSN:1229-2214 OnlineISSN:2288-6281 ✝ Correspondingauthor:wj717.lee@samsung.com,SamsungElectronicsDigitalAppliancesBusinessTel:+82-31-8062-8091 Fax:+82-31-8062-7916 |
