Author： ZYG Power Module Time： 2023-4-19
Introduction:
In this tutorial, we will learn how to build a 120V AC power supply that outputs 3V DC. This is a simple project that can be completed by anyone with basic knowledge of electronics. The power supply can be used to power small electronic projects, such as LED lights or small motors. Let\’s get started!
Materials Required:
– 120V AC power source
– Transformer (120V AC to 3V AC)
– Bridge rectifier (1N4007)
– Capacitor (1000uF, 16V)
– Voltage regulator (LM7805)
– Heat sink
– Resistor (220 ohm)
– LED
– Breadboard
– Jumper wires
Instructions:
Step 1: Connect the Transformer
Connect the primary side of the transformer to the 120V AC power source. The secondary side of the transformer should be connected to the bridge rectifier.
Step 2: Connect the Bridge Rectifier
Connect the positive and negative terminals of the bridge rectifier to the output terminals of the transformer. The bridge rectifier will convert the 3V AC output of the transformer to a pulsating DC output.
Step 3: Connect the Capacitor
Connect the positive terminal of the capacitor to the positive output of the bridge rectifier. The negative terminal of the capacitor should be connected to the ground.
Step 4: Connect the Voltage Regulator
Connect the output of the capacitor to the input of the voltage regulator. The voltage regulator is used to regulate the voltage and provide a stable 3V DC output. The voltage regulator should be mounted on a heat sink to dissipate heat.
Step 5: Connect the Resistor and LED
Connect the resistor to the output of the voltage regulator. The LED should be connected in series with the resistor. The resistor is used to limit the current flowing through the LED.
Step 6: Test the Power Supply
Connect the power supply to a load, such as an LED or small motor, to test the output voltage. The output voltage should be 3V DC.
Conclusion:
In this tutorial, we have learned how to build a simple 120V AC power supply that outputs 3V DC. This power supply can be used to power small electronic projects and is a great starting point for those new to electronics. With some basic components, this power supply can be built in just a few minutes.

Introduzione della Cina Produttori di moduli di potenza di piccole dimensioni
Quando scegliamo un modulo di alimentazione, generalmente esaminiamo la qualità dell'ingresso, dell'uscita, dell'ondulazione, del guasto, della temperatura, della certificazione e di altre caratteristiche dell'alimentatore. Oltre a questi, possiamo anche giudicare in base ai seguenti punti. 1. Principio del circuito e processo di saldatura La scheda nuda può utilizzare metodi intuitivi, come una disposizione ordinata dei componenti e dei moduli di riempimento senza essere esposta e incapace di visualizzare la situazione interna. La qualità del processo di saldatura ad onda meccanizzata è migliore della saldatura manuale, generosa, ma migliore in termini di sicurezza e prestazioni 2. Il nucleo dell'alimentazione dei componenti del chip e dei componenti del trasformatore è IC, che influenzerà direttamente la potenza e l'alto- resistenza alla temperatura del...

AC-DC Power Supply: A Reliable Solution for Efficient Electrical Conversion
Introduction: In today's technologically advanced world, reliable and efficient electrical power conversion is essential for the smooth functioning of various electronic devices. One of the key components that facilitate this conversion is the AC-DC power supply. This article aims to shed light on the importance of AC-DC power supplies and their role in ensuring efficient electrical conversion. Understanding AC-DC Power Supply: An AC-DC power supply, also known as a rectifier, is a device that converts alternating current (AC) into direct current (DC). This conversion is necessary because most electronic devices operate on DC power. The AC-DC power supply receives the AC input from the main power supply and transforms it into a stable and regulated DC output. Reliability: One of...
