The scope of this research is to manage the speed of Permanent Magnet Brushless DC Motor Drive (PMBLDCMD) for various less capacity applications. In the circuit, a 1ϕ AC power is given to Diode Rectifier and the converted DC supply is given to condenser, which leads to abnormal pulsating current. Because of this pulsating current, the power quality disturbances arise at the supply point. Hence, the PMBLDCMD requires Power Factor Correction (PFC) converter for many household and profitable applications. The rotors of PMBLDCMD are driven by 3ϕ voltage source inverter (VSI), which performs electronic commutation. The range of PFC converter for feeding PMBLDCMD has high emphasis on the power quality (PQ) norms, cost and performance of controllers. The proposed converter requires very less components, which imposes less stress, low ripple and less power loss with positive voltage polarity. The chopper is used to correct the power factor. Various chopper layouts like buck boost Converters and boost converters with single switch are used. The mostly used regulated structures for PFC converters govern the current with continuous conduction technique and to govern the potential differential tracker using discontinuous conduction method (DCM). The processes like examining, modelling and governing of PFC converters are applied for upgrading the quality of power in AC supply.
