Abstract

This study determines speed control of BLDC motor using a Bridgeless CukConverter (BCC) which enhance low conduction loss as well as lesser number of heat sink. Ascheme in which controlling voltage at output of BCC the variation in the speed of the drive is attained. Operation of cuk converter is carried out discontinuous inductor current mode at output inductance and continuous mode at input inductance and intermediate capacitors for better power factor and good power quality at AC supply mains for various speeds. On eliminating distorted currents at AC mains using filter technique to a BCC thereby improving PQ over suitable limits by IEC 61000-3-2. In this setup,supply ac mains is given to power converter. Power converter consists of BCC and VSI, voltage is varied from DC link and speed of the motor is regulated accordingly. Diode bridge rectifier(DBR) requirement is eliminated to obtain reduced conduction losses. Finally proposed system is validated in simulation and test results are obtained to get PFC at AC mains as well as operation of drive is smooth developing PQ for various range of speeds.
