3V DC آؤٹ پٹ کے لیے 120V AC پاور سپلائی بنانا

If you need a 3V DC power supply, there are a lot of options to choose from. However, if you want to build one yourself, you can do it with a few simple components. Here\’s how to build a 120V AC power supply for a 3V DC output.

Step 1: Gather Your Materials

To build a 120V AC power supply for a 3V DC output, you\’ll need the following components:

– Transformer with a 120V AC primary and a secondary output of 3V AC

– Rectifier diode (1N4007)

– Capacitor (1000uF, 25V)

– Voltage regulator IC (LM7803)

– Heat sink for the voltage regulator

– Resistor (240 ohm)

Step 2: Wire the Transformer

The transformer is the first component you\’ll need to wire. Connect the primary side to a 120V AC outlet. Then, connect the secondary side to the rectifier diode.

Step 3: Add the Rectifier Diode

The rectifier diode will convert the 3V AC output from the transformer to a DC voltage. Connect the positive side of the diode to the transformer\’s output, and connect the negative side to the capacitor.

Step 4: Add the Capacitor

The capacitor will help smooth out the voltage from the rectifier diode. Connect the positive side of the capacitor to the rectifier diode, and connect the negative side to the voltage regulator IC.

 

Step 5: Add the Voltage Regulator IC

The voltage regulator IC will ensure that the output voltage is a constant 3V DC. Connect the input pin of the IC to the negative side of the capacitor, and connect the output pin to the positive side of the capacitor. The ground pin of the IC should be connected to the negative side of the capacitor.

Step 6: Add the Resistor

The resistor will help protect the voltage regulator IC from excessive current. Connect the resistor between the voltage regulator IC\’s output pin and the positive side of the capacitor.

Step 7: Add the Heat Sink

The voltage regulator IC will generate some heat, so it\’s important to add a heat sink to dissipate the heat. Attach the heat sink to the voltage regulator IC.

Step 8: Test Your Power Supply

Once everything is wired up, it\’s time to test your power supply. Connect a 3V DC load to the output, such as an LED or a small motor. Make sure the voltage output stays at a constant 3V DC.

In conclusion, building a 120V AC power supply for a 3V DC output is a simple project that can be completed with a few basic components. By following these steps, you can create your own power supply that will provide a steady 3V DC output.

    AC-DC Power Supply Guide: The Basics of AC-DC Power Supply

    AC-DC power supplies are essential components of many electronic devices that we use in our daily lives. They convert alternating current (AC) from a power source into direct current (DC) that can be used to power electronic circuits. The basic principle behind an AC-DC power supply is the use of a transformer to step down the voltage of the incoming AC power to a lower voltage that is suitable for the electronic device being powered. The transformer is followed by a rectifier circuit that converts the AC voltage into a pulsating DC voltage. This pulsating DC voltage is then filtered by a capacitor to produce a smooth DC voltage that can be used to power electronic circuits. The transformer used...
