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.

AC-DC转换器：将交流电转换为直流电

2023-4-18

An AC-DC converter is an electronic device that is used to convert alternating current (AC) to direct current (DC). AC is the type of electricity that is produced by power stations and is supplied to our homes and businesses. DC, on the other hand, is the type of electricity that is used by most electronic devices such as computers and mobile phones. The conversion from AC to DC is necessary because most electronic devices cannot operate on AC. The AC-DC converter works by using a rectifier circuit to convert the AC input into a pulsating DC waveform. This waveform is then smoothed out using a filter circuit, which removes most of the remaining AC signal and leaves behind a relatively smooth DC signal. The output voltage of the converter can be regulated using a voltage regulator circuit, which ensures that the output voltage remains constant even when the input voltage fluctuates. One of the most common applications of AC-DC converters is in power supplies for electronic devices. These power supplies are typically found in devices such as computers, televisions, and mobile phones. The power supplies convert the AC power from the wall outlet into the DC power that is required...
Generating DC Power from AC Supply Using an AC-DC Converter

2023-4-18

In many electronic devices, a direct current (DC) power supply is essential. However, most electrical power sources, including wall outlets, generate alternating current (AC) power. To convert AC power into DC power, an AC-DC converter is needed. This article will explain how such converters work and their different types. AC-DC converters operate by rectifying the AC power supply into a DC voltage. The rectification process works by allowing current to flow in only one direction. The simplest form of rectification is achieved by using a diode, which allows current to flow only when the voltage is positive. To generate a smooth DC voltage, a capacitor can be used to filter the rectified output. There are two main types of AC-DC converters: linear and switch-mode. Linear converters use a transformer to change the voltage of the AC power supply to the desired level. The output voltage is then rectified and filtered to generate the DC voltage. However, linear converters are not efficient, as they dissipate a lot of heat due to the energy lost in the transformer. Switch-mode converters, on the other hand, use a high-frequency switching circuit to convert the AC power supply to the DC voltage. The switch-mode converter...
