Understanding Switch Mode Power Supplies (SMPS) and their Role in Efficient Electronics

The description provided discusses the use of switch mode power supplies (SMPS) in electronic equipment. It explains how SMPS have reduced the size and improved the efficiency of power supplies by increasing the frequency of operation. The description also covers the basic units of an SMPS, input protection, rectification, filtering, and voltage regulation. It further explores the challenges and considerations in designing and testing SMPS, as well as the cost and size advantages compared to linear power supplies. The environmental impact of different electricity generation sources is briefly mentioned as well.
