VARIABLE REGULATED POWER SUPPLY
INTRODUCTION
A variable regulated power supply, also called a variable bench power supply, is one where you 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. Such converters are also known as “Switch Mode Power Supply” (SMPS). 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.
