Abstract:

To correct the power factor,BL converter is used in the bridgeless configuration which feeds the DC motor drive in brushless in proposal of low power household applications. Some conduction losses reduces by brushless configuration along with diodes and some switching losses switches of the VSI (Voltage Source Inverter) which might reduce by low frequency signals in electronic commutation solid state of Brushless Direct Current Motor. Landsman Converter operation is in discontinuous flow of inductor current mode based for front-end bridgeless power factor control and used for controlling the D.C link voltage. Naturally the p.f control is attained by reduction of conduction losses and switch stress. To control DC bus voltage a sensor of single voltage is used. And we are using the fuzzy logic controller(FLC) for improving the D.C link voltage. A simulation model is to be performed for power quality improvement and for the wide range of speed control. This simulation performance for Brushless Landsman DC motor drive which is based on functions of it at diverse varying voltages of AC Mains. The range of AC Mains voltage is 90V to 265V to present the limits defined with IEC61000-3-2 which is the standard one.
