Abstract:

This paper deals with Power Quality improvement (PQI) at single phase AC mains supply for a PMBLDCM Drive using isolated CUK converter fed through a Diode Bridge Rectifier (DBR). The controller uses current multiplier approach for achieving Power Quality as per IEC-standards. The proposed drive is designed and modeled for a PMBLDC motor rated as 1.3 KW, 2300 rpm, 350 volts and 5.2 Nm. Its performance is simulated in MATLAB Simulink environment and obtained results are presented to demonstrate improved power quality at AC mains for varying speed and input voltage conditions.
