AB  - This study presents an improved power quality cuk converter fed Brushless DC (BLDC) motor drive
used for variable speed operation. In this scheme variable speed of BLDC motor is accomplished by adjusting
magnitude of DC link voltage rather than varying switching frequency of Voltage Source Inverter (VSI). The
electronic commutation of BLDC motor is achieved at fundamental switching frequency of VSI which minimises
the switching losses and thus improves the efficiency of the motor drive system. A cuk converter is connected
between diode bridge rectifier and VSI which regulates DC link voltage and improves the power quality at AC
mains simultaneously. The performance of the conventional scheme of BLDC motor is included in this study
and also the performance is tested with the speed feedback. The proposed drive scheme is simulated in
MATLAB/Simulink environment and its performance comparison is evaluated in terms of Power Quality (PQ)
over a ample assortment of speed control.
