Basic Regulated Power Supply Block Diagram

The image shows the main components of a basic power supply diagram and the waveforms at the beginning ac input at the end dc output and between blocks.

Basic regulated power supply block diagram.

Input signal which goes to the transformer primary winding is a sine wave and its amplitude depends on the country s electric distribution system 110 220 vac or other. The block diagram is implemented in ni multisim a good simulation software for students and electronics beginners i encourage spent some time playing with it. Linear switched or battery based. Commonly the bridge rectifier is used in regulated power supply.

From the diagram above it is evident that the transformer is present at the initial stage. As in my opinion you should have a strong knowledge of simulation software in order to do fun things in learning basic electronics. Its function is to convert the ac mains voltage to the rectified dc voltage. Step by step method to design 5v dc power supply.

From the block diagram the basic power supply is consti tuted by four elements viz a transformer a rectifier a filter and a regulator put together. The regulated power supply will accept an ac input and give a constant dc output. Regulated power supply block diagram a regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure. The output from an ordinary power supply is fed to the voltage regulating device that provides the final output.

The load may be connected across the voltage regulator. Regulated power supply block diagram transformer and ac supply. 1 0 1 power supply block diagram power supplies in recent times have greatly improved in reliability but because they have to handle considerably higher voltages and currents than any or most of the circuitry they supply they are often the most susceptible to failure of any part of an electronic system. The output of the dc power supply is used to provide a constant dc voltage across the load.

The basic building blocks of a regulated dc power supply are as follows. The block diagram of a regulated power supply mainly includes a step down transformer a rectifier a dc filter and a regulator. Though we had already gone through the concept regarding transformers in basic electronics tutorial let us have a glance over it. The figure below shows the block diagram of a typical regulated dc power supply.

The construction working of a regulated power supply is discussed below. It consists of rectifier filter and voltage regulator circuits. The block diagram of a regulated power supply unit is as shown below. Block diagram regulated supply.
