What is a Power supply?

A power supply is a device that provides electrical energy to electronic or electrical systems. It converts electrical energy from one form to another, typically from an alternating current (AC) to a direct current (DC) or from one DC voltage level to another, depending on the application. Power supplies are commonly used in various devices, ranging from household electronics to industrial machinery and communication systems. The primary function of a power supply is to ensure a stable power output, minimizing fluctuations in voltage and current to maintain the proper operation of the connected devices. This helps prevent damage or malfunction over time and ensures the longevity of the equipment.

There are several types of power supplies:
✅ Linear Power Supply:
Provides a stable and consistent output, typically used in precision instruments.
✅ Switching Power Supply:
Known for higher efficiency, commonly used in most electronic devices.
✅ Battery Power Supply:
A power supply that uses batteries, typically found in backup systems or mobile devices.
