Building a 120 Volt AC Power Supply for 3 Volts DC
Автор：Модуль питания ZYG Time： 2023-4-21
In this guide, we will be building a 120-volt AC power supply that can provide 3 volts DC output. This power supply will be useful for a variety of electronic projects that require a low voltage DC power source.
To begin, we will need the following materials:
– Transformer: A transformer is a device that converts high voltage AC power to low voltage AC power. In this case, we will need a transformer that can convert 120V AC to 6V AC.
– Bridge rectifier: A bridge rectifier is a circuit that converts AC power to DC power. We will be using a bridge rectifier that can handle at least 1 ampere of current.
– Capacitor: A capacitor is an electronic component that stores electrical energy. We will need a 1000uF capacitor rated for at least 16V.
– Voltage regulator: A voltage regulator is a circuit that maintains a constant output voltage. We will be using a LM317 voltage regulator that can provide a variable output voltage between 1.2V and 37V.
– Heat sink: A heat sink is a device that dissipates heat from electronic components. We will need a heat sink for the LM317 voltage regulator.
– Resistor: We will need a 240 ohm resistor to set the output voltage of the LM317 voltage regulator.
– Miscellaneous: We will also need a breadboard, wires, and a power cord.
Once we have all the required materials, we can start building our power supply. Here are the steps:
1. First, we will connect the transformer to the bridge rectifier. Connect the 6V AC output from the transformer to the AC input of the bridge rectifier. The DC output of the bridge rectifier should be connected to the positive terminal of the capacitor.
2. Next, we will connect the voltage regulator to the capacitor. Connect the positive terminal of the capacitor to the input of the LM317 voltage regulator. The output of the LM317 voltage regulator should be connected to the positive rail of the breadboard.
3. Now, we will set the output voltage of the LM317 voltage regulator. To do this, we will connect a 240 ohm resistor between the output and the adjust pins of the LM317 voltage regulator. The adjust pin should also be connected to the negative rail of the breadboard.
4. Finally, we will add a heat sink to the LM317 voltage regulator to dissipate heat. Mount the heat sink on the LM317 voltage regulator and connect it to the ground rail of the breadboard.
5. Connect the power cord to the transformer and plug it into the wall outlet. The output voltage of the power supply should be set to 3V DC.
Congratulations! You have successfully built a 120V AC power supply that can provide 3V DC output. This power supply can be used in a variety of electronic projects that require a low voltage DC power source. Remember to take caution when working with high voltage AC power, and to always follow proper safety procedures.

Если вы хотите спроектировать силовой модуль, какие аспекты необходимо учитывать?
Если вы технический инженер по импульсным источникам питания, вам не нужно смотреть на внедрение силовых модулей. Когда вы все еще новичок или изучаете дизайн SCM, лучше всего смотреть вниз слово за словом. Как правильно выбрать силовой модуль Принцип и технология схемотехники Только с профессиональной точки зрения можно различить принцип схемотехники и качество схемы. В настоящее время силовой модуль можно разделить на два типа: голая пластина и заполненное уплотнение. Необработанную плату можно интуитивно разделить на два типа, такие как разумное, упорядоченное, щедрое, упорядоченное расположение электронных компонентов, яркое пятно сварки и прямое. Но упаковка и упаковка...

Является ли специальный модуль питания лучше обычного модуля питания?
Когда вы покупаете модуль питания, вы выбираете обычный модуль питания или специальный модуль питания? В большинстве случаев доступны стандартные модули питания, в то время как специальные модули питания настраиваются специально для определенных ситуаций. Затем, в соответствии с фактическими потребностями клиентов, решите, следует ли настроить модуль питания или купить общий модуль питания. На этом высококонкурентном рынке, если предприятие хочет повысить конкурентоспособность своей продукции, оно должно сделать свои продукты определенными изюминками, и становится очень важным дифференцировать дизайн своей продукции. У всех что-то есть, вы должны делать это хорошо, у всех чего-то нет, вы должны вводить новшества. Так называемый пользовательский силовой модуль на самом деле является новым...

Efficient Industrial AC-DC Converters for Reliable Power Conversion
Industrial AC-DC converters are essential for converting alternating current (AC) power into direct current (DC) power for industrial applications. These applications include power distribution, motor control, and automation systems. The efficiency, reliability, and performance of industrial AC-DC converters are crucial for the optimal operation of these systems. Efficient industrial AC-DC converters are designed to convert power with minimal loss and deliver high-quality power to industrial loads. The efficiency of industrial AC-DC converters is determined by their power conversion efficiency, which is the ratio of output power to input power. High-efficiency industrial AC-DC converters minimize power losses and reduce the amount of heat generated during power conversion. Reliability is another critical factor in industrial AC-DC converters. Industrial environments are harsh and...
