How to Make DC Power Supply Using Proteus

Hello, friends, I hope all of you are enjoying your life. In today’s tutorial, I am going to explain How to Make DC Power Supply Using Proteus. DC power supply is the basic project that every electronic engineering student makes during his engineering. DC power supply is also used in almost every project to provide input supply to the circuitry. In this post, we will discuss in detail how to make a dc power supply and its practical implementation.

For the construction of the power supply, I will use proteus software I hope you all are aware of this software it is commonly used in electronic and engineering programs for the simulation of different project circuits. So let’s get started with the How to Make DC Power Supply Using Proteus.

How to Make DC Power Supply Using Proteus

• 7812
• The components used for this project are listed here.
• AC voltage source, it denoted as VSINE.
• Transformer it will step down the voltage provided by the AC input supply.
• The capacitor of rating 2200uf
• The resistance of one kilo-ohm
• Ground
• DC voltmeter

7812

• In this project, there is a component used that is denoted as 7812 it is a voltage regulator. It is available in integrated circuit packaging.
• This module belongs to the 78xx voltage regulators family it is easy to use and less expensive. In the name of this module, the last two digits tell about it will regulate the voltage to 12 volts.
• From the name of this module, you can observe that we will convert 220 input AC supply into 12 volts DC supply.

DC Power Supply

• To construct a dc supply in the proteus select all components mentioned above for a selection of components click on the ‘P’ button shown in the given figure and type the name of the corresponding component and select it.

• After selecting components for projects connect them with each other.

• In this project set value for AC source 220 volts and the frequency is 50 hertz as you can see in the given figure.

• After that set, the values of the transformer connected with the ac source as shown in the figure.

• After that connect the bridge circuit with the transformer secondary winding that will rectify AC output of the transformer into DC after that connect the capacitor of 2200uF with the bridge circuit.

• Now connect the voltage regulator 7812 with the circuit that will convert the output of the rectifier into 12 volts. Also, connect the red led and one-kilo ohm resistance with the voltage regulator as output.

• In the given figure, you can see the resultant circuitry.

•  As you can see in the above figure the complete circuit of the dc supply is simulated now connect the DC voltmeter across the led to see the dc output voltage which will be 12 volts.
• In the given figure, you can see the complete working circuit dc power source and 12 volts DC output voltage.

What is a Voltage Regulator?

The voltage regulator is a circuit made to maintain a constant voltage. it uses a simple feed-forward design or can come with negative feedback. it can be used as an electromechanical process or electronic component.

Based on design it is used for regulation of AC or DC voltage.

LM7812 Pinout

• Pin1 is the IN pin used as positive input voltage connection
• Pin 2 is the Ground pinout
• Pin3 is a positive output voltage pinout

Introduction to 7812 Voltage Regulator

• The 7812  is 3 terminal voltage regulator that provdies a fixed value of 12-volt output. It is used in the electronic circuit to provide a stable plus 12 volts power source for different components, like microcontrollers, sensors, and other electronic devices.
• It is used in varying loads. such as it is used to power LEDs, motors, sensors. The output current of LM7812 is about 1 ampere. So not connect the lower of larger ampere.
• It can easily be used, since easy to connect input voltage to input terminals, output voltage with output terminals and ground connection with ground terminals.
• It used in different loads such as  resistive, inductive, and capacitive loads.

Features of the 7812 Voltage Regulator

• Output voltage: 12V
• Input voltage range: 7V to 25V
• Output current: up to 1.5A
