AC-DC转换器：将交流电转换为直流电
Author： ZYG Power Module Time： 2023-4-18
An AC-DC converter is a device that is used to convert alternating current (AC) to direct current (DC). This conversion is required in many electronic devices that use DC power, such as computers, mobile phones, and televisions. In this article, we will discuss the basics of AC-DC converters, how they work, and their different types.
The basic function of an AC-DC converter is to change the direction of the current flow from AC to DC. This is done by using a rectifier circuit, which consists of diodes that allow the flow of current in only one direction. The incoming AC signal is first converted to pulsating DC signal, which is then smoothed out by using a capacitor. The output of this process is a DC voltage that can be used to power electronic devices.
There are two main types of AC-DC converters: unregulated and regulated. Unregulated converters are simple and inexpensive, but they have the disadvantage of producing an output voltage that varies with changes in the input voltage or load. Regulated converters, on the other hand, have a feedback circuit that adjusts the output voltage to a constant value, regardless of changes in the input voltage or load.
Another type of AC-DC converter is the switching mode power supply (SMPS), which is widely used in electronic devices due to its high efficiency and small size. In an SMPS, the incoming AC signal is first rectified and filtered, and then converted to a high-frequency AC signal by using a switching circuit. This high-frequency signal is then transformed to a lower voltage level by using a transformer, and finally rectified and filtered to produce a stable DC output.
In conclusion, AC-DC converters play a crucial role in powering electronic devices that require DC voltage. They can be either unregulated or regulated, and can also include switching mode power supplies for higher efficiency and smaller size. Understanding the basics of AC-DC converters is important for anyone who designs or works with electronic devices.
