The paper presents an efficient speed control of brushless DC (BLDC) motor drive for solar photo-voltaic (PV) system fed system. An interleaved boost converter is employed in the system to boost the solar PV system low output voltage to a level required for the drive system. Interleaved boost converter is operated in closed-loop mode to attain accurate and steady output. The converter (VSI) for BLDC is switched at fundamental frequency and reduces high frequency switching losses. Internal current control method is developed and employed for the speed control of PV fed BLDC motor by sensing the actual speed feedback. The appropriateness of the internal current controller for the speed control of PV fed BLDC motor is verified for incremental speed with fixed torque and decremental speed with fixed torque operating conditions. Also the system with speed control is verified for variable torque condition. The system is developed and results are developed using MATLAB/SIMULINK software.
