Soft magnetic materials (materials that can easily be magnetized) come in many forms. For switchmode power supply flyback transformers and chokes, we would consider gapped ferrites, Iron powder, ...

Magnetic cores for power supply inductors require careful selection because of the important role they play. An inductor core must be able to retain inductance with dc bias and handle any ripple ...

This article was updated Feb. 27, 2023. It was originally published Aug. 9, 2018. When a transformer fails, especially newer ones, the cost of damages can far exceed the simple replacement cost. The ...

Iron powder (IP) core flat coil inductors have become the default choice of design engineers that need to meet low inductance (0.4 to 10 µH) requirements at high currents (10 to 40 A). However, these ...

Most engineers think amorphous iron is an exotic material that is hard to come by. But the interest level in this metal is rising because its magnetic properties can promote energy efficiency in ...
