This document provides an overview of power supplies. It begins by defining a power supply as a device that supplies electrical energy to electric loads, and can convert one form of energy to another. It then discusses the basics of power supplies, including the different types (conventional, switching, battery, etc.), their attributes, and common applications. The document uses visuals like diagrams and images to aid the explanation of power supply fundamentals and help the reader understand this important electrical component.
