电脑电源主要由以下几个部分组成：输入电路、整流电路、滤波电路、功率转换电路、输出电路和保护电路。其中，输入电路负责接收外部电力，整流电路将交流电转换为直流电，滤波电路用于滤除电源中的杂波，功率转换电路则是将直流电转换为电脑各部件所需的电压。 二、电脑电源的工作原理 1. 接收外部电力：电源通过线缆接入到墙壁插座或者UPS设备，接收到外部电力。 2. 整流和滤波：通过整流电路将交流电转换为直流电，然后通过滤波电路滤除杂波，使电源输出的直流电更加纯净。 3. 功率转换：功率转换电路是电脑电源的核心部分。它根据电脑各部件所需的电压和电流，将直流电转换为合适的电压输出。这个过程需要高精度的控制，以保证电源的稳定性和效率。 4. 输出电力：转换后的电力通过输出电路供应给电脑的各个部件。同时，保护电路会在必要时启动，以保护电源和电脑的其他部件免受损坏。 三、英文翻译 Revealing the Secrets of How Computer Power Supply Works: How Does Your Computer Get Electricity? In a computer, the power supply is a crucial part that provides electricity for all the components of the computer. So how does the computer power supply work? This article will delve into the working principles of the computer power supply. I. Composition of Computer Power Supply The computer power supply is mainly composed of the following parts: input circuit, rectifier circuit, filtering circuit, power conversion circuit, output circuit, and protection circuit. The input circuit is responsible for receiving external power, the rectifier circuit converts AC power into DC power, the filtering circuit is used to filter out noise in the power supply, and the power conversion circuit converts DC power into the voltage required by each component of the computer. II. Working Principles of Computer Power Supply 1. Receiving external power: The power supply is connected to a wall socket or UPS device through a cable to receive external power. 2. Rectification and filtering: The AC power is converted into DC power through the rectifier circuit, and then filtered through the filtering circuit to make the DC power output by the power supply more pure.

3. Power conversion: The power conversion circuit is the core part of the computer power supply. It converts DC power into appropriate voltage output according to the voltage and current required by each component of the computer. This process requires high-precision control to ensure the stability and efficiency of the power supply. 4. Output of electricity: The converted electricity is supplied to each component of the computer through the output circuit. At the same time, the protection circuit will activate when necessary to protect the power supply and other components of the computer from damage.
