![]() It has two terminals that are connected with two parallel conductor plates and they are separated from each other with an insulating material called dielectric material.Capacitors are electronic components that have the ability to store energy.We are using the diodes as rectifiers in this project.There are various types of diodes available but as per our use case, we will use a simple PN junction type diode.In N-type semiconductors, free electrons are in majority, and in P-type semiconductors, holes are in majority.A simple PN type diode is made using the P-type and N-type semiconductors.The P side terminal is also known as Anode and the N side terminal is known as Cathode.As per the construction, it has two sides P side and N side.It has two terminals as Anode and Cathode and current is allowed to flow from Anode to Cathode side only.They are used mostly in every electronic device such as in power supply or as regulators or used in construction ICs for logic gates. ![]() It works as a valve which allows the flow of current in only one direction and limits the flow of current in another direction.Diodes are two-terminal simple electronics components.In this type of transformer, there are more turns on the primary side winding and lesser turns on the secondary side winding.It is the exact opposite of the Step-up transformer as per the use case and windings.Here we will not go in-depth about the working of transformers but in brief, it has two windings as primary and secondary.It takes high voltage and low current as an input and it will give low voltage and high current as an output.Step down transformer is used to convert the high input voltage to low voltage.For more details about this IC prefer the following datasheet:.As per the datasheet, it has a formula for calculating output voltage, and using that we can adjust our resistor value as per our requirement of output voltage.It uses one resistor for the RC filter and one as a potentiometer to adjust the output voltage.It is a very easy-to-use IC, it requires only two resistors for the circuit and it will be ready to use.As the name suggests, the Vin pin is used for the input power supply, the Vout pin is used to take the output voltage, and Adjust pin is used to control the output voltage.Using these three pins only we can regulate the output voltage.It has three terminals as Vin, Vout, Adjust.It is a voltage regulator IC which has a wide range of applications in various voltage limiting circuits.Three 0.1 microFarad non-polar capacitors.One 4700 microFarad Polarised capacitor.It has a very large database of pre-installed components which has basically all types of different electronic components and in case, if it is not pre-installed, then we can install a library for those. Also, we can easily debug in case of a wrong connection. A brief about the Proteus, it is a simulation software for electronics, here we can make different types of electronic circuits and run the simulation and it will give us the real-time working model of our circuit. To make this project we will be using the Proteus simulation tool. We will make this project in the simulation, as it is a good practice to make any project in the simulation first so that if we do any mistakes or errors in the circuit, which can be corrected without making any physical damage to actual components. So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply.
