Tailoring is one of the most important livelihoods in India. Manual sewing machines were used by traditional tailors who generally serve local customers in small cities and villages. To strive on the existing market and to gain higher productivity some of them have modified their machines by retrofitting the motor. However, in rural areas with few or no grid availability, it is difficult to meet the growing demands. Hence solar is an ideal solution for micro generation for peoples in villages and for tailors in small cities. So this project work uses solar energy for generation of electricity which will be fed to motor of sewing machine. VS enterprises
The maximum power point tracking concept is generally use for extracting highest power point available from PV module. MPPT method is utilized to enhance the productivity of the solar panels. MPPT techniques are of different types which includes Fuzzy Logic Method, Perturb and observe (P&O), Incremental conductance method, Constant voltage Method. Among the above techniques, P&O algorithm is the most simplest one hence this technique is used for controlling the step-up converters duty(D), D is calculated and converted to digital pulses using repeating sequence, sum and compare to zero block. In this technique power yield of system is checked by changing the input solar voltage. The nth sample indicates the present value and (n-1)th indicates previous value. If the voltage value increments on increment in power value then the duty cycle value should be decreased otherwise duty should increase. Another condition is if the voltage value increments on decrement in power value then the duty cycle should increase otherwise duty should decrease.
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.https://www.vssewingmachine.in/
