A transformer is an electrical device that transfers energy from one circuit to another purely by magnetic coupling. Transformers are often used to convert between high and low voltages, to change impedance, and to provide electrical isolation between circuits. A transformer doesn't change power levels, though. If you put 100 Watts into a transformer, 100 Watts come out the other end. Actually, there are minor losses in the transformer because nothing in the real world is 100% perfect. But transformers come pretty darn close; perhaps 95% efficient.
This course presents the basics of transformers including transformer action, transformer components, and transformer design. It also covers the essential operational principles behind transformers, as well as practical matters such as power losses and transformer efficiency. Finally, the course discusses different applications of various transformer types and concludes with a brief look at some safety precautions to take when working with transformers.
