Introduction to Switched Mode Technology
Switched mode technology, often referred to as switched mode power supply (SMPS), has revolutionized the way we convert and manage electrical energy. It provides efficient power management solutions in various applications, from consumer electronics to industrial equipment. With the growing demand for energy efficiency and compact design, switched mode technology is becoming an essential component in modern electrical systems.
Types of Switched Mode Power Supplies
There are several types of switched mode power supplies, each designed to cater to different applications and requirements. Below are the primary types:
- AC-DC Converters: Converts alternating current (AC) from the mains into direct current (DC).
- DC-DC Converters: Converts one level of DC voltage to another, adapting to various electronic needs.
- DC-AC Inverters: Converts DC power back into AC for various uses, including renewable energy applications.
- Isolated versus Non-Isolated Supplies: Isolated supplies provide galvanic isolation between input and output, while non-isolated supplies do not.
Function and Features of Switched Mode Power Supplies
Switched mode power supplies are engineered to convert power efficiently using a variety of operational features. Their functionality and remarkable characteristics include:
- High Efficiency: Switched mode power supplies typically achieve efficiencies of 80-95%, depending on design.
