BLDC Motor Control Using PV fed ZETA Converter
Abstract
This paper proposes a zeta converter fed photovoltaic array as input power source for effective control of BLDC motor. The maximum power available from the SPV array is attained and it is conveniently utilized by the Zeta converter. The voltage source inverter (VSI) is used to perform electronic commutation of the BLDC motor and it plays a vital role in avoiding switching losses caused by the high frequency switching pulses. The output power of the zeta converter is used to drive the BLDC motor. The speed control of BLDC motor is resolved by governing the switching pulses of VSI by the electronic commutation of the BLDC motor. The suitability of proposed system at different possible operating conditions is exhibited through simulation results using MATLAB/ Simulink software.
