| Abstract: | Due to the limitations of single-phase power supply as well as the advantage of the three-phase power supply,high power air-conditioners should be powered by three-phase supply with passive power factor correction scheme.Considering the effects of correction,cost,size,weight,efficiency,output voltage and other aspects,the key issues for uncontrolled rectifier with single-stage LC filter are proposed,including principle of harmonic source equivalence,principle of harmonic current filter,increase of output DC... |
