Understanding the basic knowledge and principles of the computer power supply is of great significance for maintaining the normal operation of the computer and extending its service life. Part Two: Basic Knowledge of Computer Power Supply 1. Definition: The computer power supply is a device that converts AC (Alternating Current) to DC (Direct Current) power, mainly providing a stable power supply for various computer components. 2. Composition: The computer power supply is mainly composed of a transformer, rectifier, filter, and other parts. Part Three: Working Principles of Computer Power Supply 1. AC Conversion: The computer power supply first converts household AC power into low-voltage AC power through a transformer. 2. Rectification: Then, the low-voltage AC power is converted into pulsating DC power through a rectifier. 3. Filtering: Next, impurities in the pulsating DC power are removed through a filter, making it more pure. 4. Voltage Stabilization: Finally, the voltage is stabilized within an appropriate range through a voltage regulator circuit, providing a stable power supply for various computer components.
