How to Build an AC-DC Power Supply
المؤلف ： ZYG Power Module Time： 2023-4-19
Building an AC-DC power supply is a useful skill for anyone who wants to create their own electronic devices. AC-DC power supplies are used in a wide range of applications, from powering small electronic devices to providing the necessary voltage for larger projects. In this article, we will go through the steps to build an AC-DC power supply.
Step 1: Planning
Before you start building the power supply, you need to decide what voltage and current ratings you require. You should also decide if you want a regulated or unregulated power supply. A regulated power supply provides a constant voltage output, while an unregulated power supply output varies with changes in input voltage and load.
Step 2: Choosing a Transformer
The first component you need to choose is the transformer. The transformer converts the input voltage (usually 120VAC in the US) to a lower voltage, typically between 6V and 24VAC. You can find transformers of various sizes and ratings at electronics stores or online retailers.
Step 3: Building the Rectifier
The next step is to build the rectifier. The rectifier converts the AC voltage to a DC voltage. There are several types of rectifiers, including half-wave, full-wave, and bridge rectifiers. The bridge rectifier is the most efficient and commonly used type. You can purchase ready-made bridge rectifiers or build your own using four diodes.
Step 4: Filtering the DC Voltage
The DC voltage output from the rectifier will still have some AC ripple, which can cause problems for your electronic devices. To filter out the ripple, you can use a capacitor. Choose a capacitor with a voltage rating that is higher than the DC voltage output and a capacitance value that is appropriate for your application.
Step 5: Regulating the Voltage (Optional)
If you need a regulated voltage output, you can add a voltage regulator to your power supply. There are many types of voltage regulators available, including linear and switching regulators. The linear regulator is the simplest and most commonly used type.
Step 6: Building the Enclosure
Once you have assembled your power supply, you need to build an enclosure to protect it from damage and contain any electromagnetic interference. You can use a metal or plastic box with ventilation holes and mounting points for the transformer, rectifier, capacitor, and regulator.
Step 7: Connecting the Components
Finally, you need to connect the components together and test the power supply. Make sure to follow the wiring diagram carefully to avoid any wiring mistakes. You should also test the output voltage and current to ensure that they meet your requirements.
In conclusion, building an AC-DC power supply is a rewarding experience that can help you save money and learn about electronics. With the right components and some basic knowledge, you can build a power supply that meets your specific needs.

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...
