The simulation model of complete drive is developed in MATLAB-SIMULINK and simulated response of proposed drive is obtained under various operating conditions. The hardware prototype setup is also developed in the lab for the validation of the simulation results. The obtained Simulation and hardware results are presented to demonstrate the feasibility of a SPV system based PMBLDCM drive. Keywords— PV Array; VSI; PMBLDCM Drive I. INTRODUCTION Permanent Magnet Brushless motor is mostly used in the low power applications. It has the high efficiency rugged construction and easy of control to be used for speed control applications. Three- phase voltage source inverter (VSI) or current source inverter (CSI) is required to control the PMBLDC Motor using its rotor position information. Hall sensors are used for the rotor position sensing. These sensors increase the size, cost and complexity of PMBLDCM drives. Recently, PMBLDCM drives are used in electric vehicles (EVs) and Hybrid electric vehicles (HEVs) due to the environmental concern vehicular emissions [1-5]. At present, we have the crises of fossil fuel, conventional resources such as coal, Petroleum and Natural gas. Due to the pollution problem, Green house effect and CO2 emission, humankind is trying to utilize the non conventional resources in an appropriate way. Advanced technologies are increasing for utilization of renewable energy in different applications. Amongst various renewable energy sources, Solar Energy plays an important role in recent scenario. Because of the free availability of solar energy, it can be use for different applications like water heater, solar cooker, solar water pump, solar street light etc. For the electricity extraction, solar photovoltaic systems consisting of semiconductor cells, which convert the solar energy into electricity, are used in different applications. The output of SPV system depends upon the solar radiation and temperature. Maximum power point tracking (MPPT) is required for the maximum energy extraction from SPV systems. As a thrust area, researchers are trying to increase its efficiency, reliability and ease of handling [6-7]. This paper presents a standalone solar PV system based PMBLDCM drives for low power applications. The PV module supplied to VSI for driving the PMBLDC motor. The proposed system includes PV module, three phase VSI, and PMBLDCM drive. The experimental setup is implemented for the practical analysis of proposed system. II.
