Abstract


This paper deals the Brush Less DC Motor (BLCDM) driven by an efficient closed loop fuzzy logic based high voltage gain interleaved boost converter. The proposed high voltage gain interleaved boost converter in this paper is to boosts an input DC voltage to required DC output voltage. The proposed converter performs the inverter operation to drive the BLCDM. For fine tuning and dynamic responses of BLDCM, such as speed, torque, stator current and stator voltage an improved closed loop fuzzy logic control method is adapted in this paper. The control technique is modeled and simulated in MATLAB 2009a GUI environment using Simulink and Sim Power System set tool boxes.  Finally the resultant simulation waveforms shows some more accuracy with the proposed closed loop fuzzy logic control technique as compared with conventional control techniques. The control techniques to drive the BLDCM are modeled and simulated in MATLAB 2009a GUI environment using Simulink and Sim Power System set tool boxes
