BATTERYLESS POWER SUPPLY USING PV CELLS AND MPPT

ELECTRONICS AND COMMUNICATION ENGINEERING

The main objective of our project is to enhance power from renewable sources (solar). A photovoltaic silicon cells are embedded in a lamination sheet consisting of 40 solar modules, heat generating a voltage of 1.2v DC for continuous power generation all the modules are connected in series to generate a voltage of 63v DC. The voltage is amplified by means of buck boost converter which compresses 63v to 20v DC. The circuit amplifies the current of 500mamps to generate a proper load, solar is abundant in nature. The motto of our project is to give the load directly without the means of battery. We conclude that our project gives an output of 12v-50w output. The energy consumed by the load and the balance energy will be transmitted to electrical DB to store the energy. A display driver is implemented to monitor the voltage current power import and export. To see the exact values generated and displayed through LCD. A voltage and current sensors are connected as input to the display driver the power supply of 5v is given to the input of display driver. This electronic circuits is only meant for monitoring the values generated from our PV cells.
