Abstract: BLDC motors are expected to be one of the fastest growing end product for household applications as well as irrigation purpose due to its electronic commutation feature, good running performance and overall efficiency. These motor drives, when combined with the use of power electronic converters poses challenges in power quality in terms of reduced supply power factor. In order to overcome these problem, it is proposed to employ a bridgeless LUO converter in BLDC Motor Drive system. The LUO converter possess high voltage transfer gain, high power density, reduced ripple voltage and current, thereby leading to improved power factor. The proposed scheme is modelled in MATLAB/Simulink platform and are simulated to find out the power factor and torque behavior. The results indicate the satisfactory performance of the proposed scheme in terms of power factor improvement and reduced ripple in electromagnetic torque waveform.
