Design And Implementation Of PFC CUK Converter-Based PMBLDCM Drive

摘要

This method is used to improve the efficiency of motor drive by power factor correction. It plays an important role in energy saving during energy conversion. A cuk dc -dc converter topology reduced the power quality problems and improve the power factor at input ac mains. A three-phase voltage-source inverter is used as an electronic commutator operates the PMBLDCM drive The concept of voltage control at the dc link proportional to the desired speed of the PMBLDCM is used to control the speed of the compressor. The proposed power factor converter topology is designed, modeled and its performance is evaluated in matlab-simulink environment. The results show an improved power quality and good power factor in wide speed range of the drive. It also compares the Total Harmonic Distortion (THD) of the Input AC current with PID controller in Matlab-Simulink environment.
