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.

Set Up

A DSP based closed-loop system has been developed for wind-driven three-phase Self-Excited Induction Generators (SEIGs) using a diode bridge rectifier (DBR) followed by an IGBT inverter. This system is meant for supplying isolated ac loads with a voltage of constant magnitude and frequency, for any operating condition of varying nature of wind speed and consumer load. The configuration and implementation of this proposed system have been fully described. The detailed method of analysing and predetermining the performance characteristics of such stand-alone systems has also been explained. Test results obtained on an SEIG operated with the controller built in the laboratory, demonstrate the successful working of both the hardware and software of the control scheme and the usefulness of the set-up as a whole for supplying isolated ac loads. With the varying nature of wind speed, a method of meeting the power balance between the wind power available and the load power requirement has also been explained with extensive Simulation studies.
