This paper present about the design of a power factor corrected bridgeless Buck- boost converter fed Brushless motor drive. The Brushless DC motor (BLDC) is used as a solution for a cost effective and low power motor drive. By controlling the DC link voltage of the BLDC motor drive, the speed of the drive is adjusted. The voltage source inverter (VSI) is fed by this DC link voltage. This makes the VSI to operate at fundamental frequency switching which utilizes the electronic commutation of BLDC motor. The bridgeless configuration of the Buck-boost is used to eliminate the switching losses related with the diode bridge rectifier and is operating in the discontinuous inductor current mode, so that it provides an inherent PFC at AC mains. In this paper by varying the supply voltage and wide range of speed control, performance of the drive is analyzed. The steady state and dynamic analysis of the system is performed in MATLAB/SIMULINK environment.
