Welcome to this installment of EE Classroom on Transformers.
Electronics may not be simple but there are devices that are simple – and simply elegant – but which still require an understanding of the challenges they can present when integrating into a design. Transformers are such a device; a device that is “simply” a pair of inductors magnetically coupled to enable electromagnetic induction between them. From electromagnetic induction to the coefficient of coupling to the turn, voltage, and current ratio, there are plenty of points to consider when working with transformers.
In this classroom, you’ll learn some of the dos and don’ts while working with transformers, as well as types, applications, and design considerations. Get to know the material properties and geometric of magnetic cores used in power inductors. Learn when Electromotive force (EMF) can become Electromagnetic Interference (EMI) when induced current happens where it’s not wanted. Lower voltage circuity may be the trend but what if your design takes you down the high-voltages path? The two-part FAQ on voltage boosters and voltage multipliers can help you set your course. What about the flyback power converter topology? The basics of this 70+ approach hasn’t changed (much) but you can refresh your knowledge and learn more about how enhancements and ICs fit into flyback design. And don’t forget to check out the more detailed guides to transformers from our sponsor.
