Power Supply

A power supply is an electronic device that converts electrical energy from one form to another to provide the correct voltage, current, and frequency to power electronic circuits and devices. It typically converts AC mains power (like wall outlets) to stable DC voltages, or steps voltage levels up or down as needed by the connected equipment. Power supplies include various types such as linear regulators, switching regulators, and battery chargers, and often incorporate protection features like overcurrent and overvoltage safeguards to ensure safe and reliable operation.
