Regulated Dc Power Supply Block Diagram. The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. Transformer stp up or step down input transformer for the stepping up or down ac power supply.
This circuit is based on ic lm7812. A regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure. Step by step method to design 5v dc power supply.
It consists of rectifier filter and voltage regulator circuits.
The basic building blocks of a regulated dc power supply are as follows. Its function is to convert the ac mains voltage to the rectified dc voltage. Step by step method to design 5v dc power supply. Commonly the bridge rectifier is used in regulated power supply.
