SEPIC Based PFC Converter for PMBLDCM Drive in Air Conditioning System
نویسنده
چکیده
In this paper, A power factor correction (PFC) based single ended primary inductor converter (SEPIC) is used to regulate DC bus voltage of voltage source inverter (VSI) to run PMBLDC motor . Permanent magnet brushless DC motor (PMBLDCM) is used in air-conditioning systems and runs at rated torque and variable speed to achieve energy conservation. The analysis, design and performance of the proposed PFC converter is carried out for a 1.2 kW, 1200 rpm, 164 V PMBLDCM used in air-conditioning system. The PFC converter is modeled and its performance is simulated in Matlab-Simulink environment. The improved power factor of the drive is evaluated in wide range.
