SHAYAN SAEED TC-35 PROJECT: DC POWER SUPPLY FATIMA TANOLI TC-08 RAHIM ARSHAD TC-23 MAHNOOR ADNAN TC-12 HUZAIFA YOUNUS TC-27 CIRCUIT DIAGRAM: Components Needed • AC Plug12V • Transformer • Full Wave Bridge Rectifier • LM317 Voltage Regulator • 1000μF electrolytic capacitor • 1K Resistor • 10KΩ Potentiometer AC Plug When we create a DC power supply, it creates DC voltage from the AC mains voltage from a wall outlet. Transformer The transformer's activity is to take the 220V AC voltage from the mains line and step it right all the way down to 12 volts because we are using a 12V transformer. Full-wave Rectifier The activity of the full-wave rectifier is to take the AC voltage from the transformer and rectify it in order that there is no negative cycle. Filter Capacitor The Filter capacitor acts to clean out fluctuations in a signal, in order that there may be much less fluctuation. LM317 Voltage Regulator it serves as an adjustable voltage regulator, is to provide variable DC voltage as output. Potentiometer These used collectively determine what voltage might be output with the aid of using the regulator.
