Make your own Variable DC Power Supply

Fully Regulated Variable DC Power Supply

Project by: Engineer Hafiz Yasir Qureshi NUST Pakistan

Introduction

The project “VARIABLE REGULATED POWER SUPPLY” plays a very important role in the laboratory functions and that is mainly to the electronics labs. As in electronics all the instruments, components work on a particular regulated dc supply ,so a project which can provide this supply by converting the alternating current to direct current that too into a great range of regulated power keep its own preference. As it can produce a range of 0-30 v direct current by regulating and converting alternating current is has a vast application too. AC to DC converters generally comprise a rectifier bridge to rectify the AC current of the input line and a regulating device supplying on output of one or more regulated DC voltages. Just the simple ac current is applied and through potentiometer you get the desired regulated dc power supply.
