The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

The principle of action and reaction in Lenz’s Law states that an induced electromotive force (emf) generates a current in a direction which opposes the change in flux that caused the emf in the first ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...
