Implementation of Solar Powered BLDC Motor Drive

Renewable energy sources are being increasingly implemented in many applications due to the growing concern of environmental pollution. The PV (Photovoltaic) system appears to be most promising one because it is environmentally clean in nature and it directly converts solar energy into electrical energy. This paper presents the FPGA (Field programmable gate array) based speed control of PMBLDC (Permanent magnet Brushless DC) motor & this BLDC motor is driven by the solar energy. The solar panel is used to obtain the energy needed to run BLDC motor. The voltage obtained from solar panel is stored in battery due to the non-constant nature of solar energy. The voltage from battery is not sufficient to run BLDC motor & hence boost converter is used to boost the voltage required to run BLDC motor. Commutation is implemented on FPGA. FPGA based speed control scheme reduces the complexity of motor control hardware & in turn boost the demand for mobile applications.
