This work focuses on photovoltaic array fed sewing machine. Main focus is on utilizing non conventional energy resources i.e. solar energy because now-a-days the entire world is facing crises of energy. System consists of an arrangement of several components, including solar panels to absorb and convert sunlight to electricity. In this research work a photovoltaic array is used to run a motor i.e. dc motor that drives the sewing machine. Dc motor will be fed by charge controller and the duty cycle of charge controller is controlled by using MPPT (P&O) algorithm. The simulink model of the research work is done using MATLAB software.
Solar panel is the input energy and the output terminals of it are fed to the controller circuit. A storage device i.e. battery is used to store the charges of solar panel and the two output terminals of battery are connected to the charge controller to get good efficient solar operation. The pedal controller is connected to the charge controller. Pedal controllermonitors the speed of the motor. Hence we can say solar panel, battery and pedal controller are simultaneously connected to the MPPT controller unit. Motor of sewing machine is connected to the pedal controller. In this way the solar panel is use to run sewing machine.
Photovoltaic change is the immediate transformation of daylight into power without mediating heat engine. They are strong state devices and henceforth they are tough and fundamental in design and require next to no upkeep. When exposed to the sunlight, a solar board essentially is a p-n semiconductor junction which generates DC current sewing machine dealers in chennai
In accordance with the above equations (1), (2) and (3) it is possible to build the block of complete solar panel in MATLAB Software, the complete block allows simulating the non-linear current vs. voltage and power vs. current graph. Fig 3 shows the mathematical block of solar panel. This block consists of three inputs solar irradiance, voltage and temperature and one output i.e. current. Temperature block is having constant value of 25ºC, internal block arrangement will convert it into Kelvin. Signal builder block is used for variable irradiance values for generating variable I-V and P-V curves. Load Voltage repetition table is the third input to the PV block.
