Autor： Módulo de potencia ZYG Time： 2023-4-24
Introduction
A power supply is an electronic device that is used to convert one form of electrical energy into another form. It is an essential component of any electronic device that requires electrical power. In this article, we will discuss how to build a 120-volt AC power supply for 3-volt DC conversion.
Components Required
The following components are required to build a 120-volt AC power supply for 3-volt DC conversion:
1. Transformer
2. Diodes
3. Capacitors
4. Resistors
5. Voltage Regulator
6. LED
7. Breadboard
8. Wires
9. Soldering iron
10. Multimeter
Step-by-Step Guide
1. Transformer: The first step is to choose a transformer that can convert 120-volt AC to 3-volt AC. You can use the following formula to calculate the voltage rating of the transformer:
Secondary = Vprimary / N
Where Vprimary is the voltage rating of the primary winding, Vsecondary is the voltage rating of the secondary winding, and N is the turns ratio.
2. Diodes: The next step is to connect four diodes in a bridge rectifier configuration. The diodes are used to convert AC voltage into DC voltage. The bridge rectifier configuration ensures that the output voltage is always positive.
3. Capacitors: The next step is to connect two capacitors in parallel across the output of the bridge rectifier. The capacitors are used to smooth out the DC voltage.
4. Resistors: The next step is to connect a resistor in series with the LED. The resistor is used to limit the current flowing through the LED.
5. Voltage Regulator: The next step is to connect a voltage regulator to the output of the capacitors. The voltage regulator is used to regulate the voltage to 3 volts DC.
6. LED: The next step is to connect an LED in series with the resistor. The LED will indicate when the power supply is on.
7. Breadboard: The next step is to connect all the components on a breadboard. A breadboard is a device used to build and prototype electronic circuits.
8. Wires: The next step is to connect the components on the breadboard using wires. The wires should be of the appropriate gauge and length.
9. Soldering Iron: The next step is to solder the components on the breadboard. Soldering is a process of joining two metal surfaces using a soldering iron and a solder wire.
10. Multimeter: The final step is to test the power supply using a multimeter. The multimeter is used to measure the voltage and current of the power supply.
Conclusion
In this article, we have discussed how to build a 120-volt AC power supply for 3-volt DC conversion. We have discussed the components required and the step-by-step process to build the power supply. It is important to remember that electronic circuits can be dangerous and should only be attempted by those who have the necessary knowledge and experience.

Transforming Power: The AC-DC Converter
Power is an essential component of modern life, powering everything from the devices we use in our homes to the machinery used in factories. However, the form in which we receive power from the grid is alternating current (AC), while many of the electronic devices we use require direct current (DC). In order to convert AC power to DC power, we use AC-DC converters. AC power is generated by power plants in the form of a sine wave, with a frequency of 50 or 60 Hz, depending on the region. This AC power is then transmitted through power lines to reach households and businesses. However, many electronic devices require a steady DC voltage to operate. This is where AC-DC converters...
