Power Quality Improvement of BLDC Motor Drive using Cuk PFC Converter

In this paper cuk dc-dc converter fed BLDC motor drive is described. Power quality issues have been improved by using cuk power factor correction (PFC) converter. In this system speed control is attained by maintaining proportionality between speed and dc link voltage. Modeling and performance evaluation is done with Matlab-Simulink. It results in unity power factor and reduction in harmonics. Cuk converter is compare with conventional boost PFC converter using Matlab. It leads to Cuk converter as good alternative solution for low power application.
