About china AC-DC Power Supply

The power supply can be external, typically found in devices like laptops and phone chargers, or internal, such as in larger devices like desktop computers.

The power supply can be regulated or unregulated. In a regulated power supply, changes in the input voltage do not affect the output. On the other hand, in an unregulated power supply, the output depends on any change in the input. What all power supplies have in common is that they take power from the source at the input, convert it in some way, and deliver it to the load at the output. Input and output power can be alternating current (AC) or direct current (DC):
Direct current (DC) occurs when current flows in one constant direction. It usually comes from batteries, solar cells, or AC/DC converters. DC is the preferred power source type for electronic devices.

 

 

 

Alternating current (AC) occurs when an electrical current periodically reverses its direction. Alternating current is the method of supplying electricity to homes and businesses through power lines.

So if AC is the type of power supplied to your home and DC is the type of power you need to charge your phone, then you will need an AC/DC power supply to convert the AC voltage from the power grid to the DC needed to charge your phone battery Voltage.

An AC-DC converter is an electronic device that converts alternating current (AC) to direct current (DC). This is a common requirement in electronic circuits as most electronic components require DC for proper operation. In this article, we will discuss how to build an AC-DC converter. Step 1: Determine the Voltage and Current Requirements The first step in building an AC-DC converter is to determine the voltage and current requirements for your application. This will depend on the specific electronic components you are using. For example, if you are powering an LED, you may require a low voltage (e.g. 5V) and a low current (e.g. 20mA). On the other hand, if you are powering a motor, you may require a higher voltage (e.g. 24V) and a higher current (e.g. 2A). Step 2: Choose the Type of Converter Circuit Once you have determined the voltage and current requirements, you need to choose the type of converter circuit you want to use. There are two main types of AC-DC converter circuits: the half-wave rectifier and the full-wave rectifier. The half-wave rectifier circuit only uses one diode to convert the AC input to DC output. This is a simple and inexpensive circuit, but it...

AC-DC コンバーター: 交流を直流に変換

2023-4-17

An AC-DC converter, also known as a rectifier, is an electronic device that is used to transform alternating current (AC) into direct current (DC). This process is essential in many applications where DC voltage is required, such as in electronic devices and power supplies. The conversion process involves a diode bridge rectifier that allows the AC current to pass through in only one direction, effectively converting it into DC voltage. This rectifier is made up of four diodes that are arranged in a specific pattern to create a bridge circuit. During the positive half-cycle of the AC voltage, one pair of diodes conducts and allows the current to flow through them, while the other pair of diodes is reverse-biased and blocks the current. The opposite happens during the negative half-cycle, where the previously conducting diodes are now reverse-biased, and the other pair of diodes conduct. The output of the rectifier is a pulsating DC voltage, which is not suitable for most applications. Therefore, a smoothing capacitor is added to the circuit to filter out the pulsations and create a more stable DC voltage output. The size and capacity of the smoothing capacitor depend on the application and the amount of...
