Description
BSTRACT
The scope of this project is to design, develop and test a power supply capable of taking an ac voltage and convert it into a regulated low voltage. The main working of this project is a full wave rectification which is done by bridge configuration in which four diodes are used to rectify the output the step-down transformer which steps down the voltage from 240v to 12 V.A Voltage Regulator is then used which gives a constant voltage. The main task is to get variable output by using the pair of voltage divider resistance to increase the output of the regulator in which the resistance is variable. So when increasing or decreasing the resistance of the resistor, also the voltage varies from 1Vto 12 V.The circuit also uses capacitors C1 and C2 to get constant input voltage to the regulator and also is used tosmoothen the rectified voltage to output.The power supply will be connected to the Zener voltage regulator that could supply to the load.
