With the continuous advancement of computer technology, our dependence on its internal components has deepened. Among them, the computer power supply (or power source) is an indispensable part of computer hardware. It provides stable and sufficient power for various parts of the computer to ensure its stable operation. This article will provide a detailed explanation of the working principles of the power supply. I. Basic Structure of Power Supply The power supply is mainly composed of the following parts: 1. Input end: Receives external power, usually alternating current (AC). 2. Rectifier circuit: Converts AC power into direct current (DC). 3. Transformer circuit: Adjusts the voltage and current of DC power to appropriate levels. 4. Output end: Provides stable DC power to the computer motherboard and other devices. II. Working Principles of Power Supply The working principles of the power supply can be summarized as the following steps: 1. Power reception: The power supply receives external power through the input end, usually AC power from household appliances.

2. Rectification: The rectifier circuit converts AC power into DC power through electronic components such as diodes.
