A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
Key components of a power supply include transformers, rectifiers, filters, voltage regulators, and protection circuits. Understanding the functions and components of power supplies is crucial for designing and operating electronic systems effectively.
Sep 21, 2021 · Components. How to Choose the Best PC Power Supply. Whether you're upgrading your desktop PC or building one out from scratch, here's what you need to know about finding the right PSU,...
Power supplies are primarily used for changing voltage. The power source has a steady output, regardless of the device that must be used. To prevent overload, power supplies step down the voltage—or, conversely, step it up—to match the device’s requirements.
The power supply uses a transformer to step down the high voltage AC, then a rectifier to convert AC to DC, and further adjusts it to precise voltage levels. 2. Voltage Regulation and Stabilization. Besides converting voltage, a power supply must provide a stable voltage output to meet device demands.

Power supplies are electrical devices that deliver electric power to one or several loads. They generate the output power by converting an input signal into an output signal with some different characteristics. The input and output power can both be a direct current (DC) or alternating current (AC) signal.
