In this paper ,a new approach is presented aim at improving the power factor of three phase bridge inverter that equip with permanent Magnet Brushless DC motor(PMBLDCM)drive through microcontroller. Power factor correction converter is used for feeding a three phase bridge inverter based PMBLDC motor drive. The front end of PFC converter is a diode bridge rectifier fed from a step down transformer. In this three phase bridge inverter is operated as electronic commutator of the PMBLDCM .Nearly sinusoidal input current is achieved using. The proposed PMBLDCM drive with PFC converter is designed to run the motor to desired speed. This scheme improves an efficiency of proposed drive system with PFC feature in wide range of the speed and an input AC voltage.

In this paper, performance of voltage source inverter.(VSI) fed Permanent Magnet Brushless DC Motor(PMBLDCM) with Power Factor Correction (PFC) is discussed. A power factor correction converter is suggested at the input to correct the power factor on the input side. The conventional circuit is improved by introducing double boost converter at the input side. The Pulse Width Modulation (PWM) inverter fed Permanent Magnet Brushless DC motor system with L-filter, T-filter and double boost converter are simulated and the results are presented. The performance of PMBLDCM operating with the above mentioned converters is studied. By digital simulation, the characteristics of the PMBLDCM system are investigated. FFT analysis for various converters is presented. The simulation results indicate improved performance.
