Preface to Magnetic Components Power Electronics PDF

Power electronics is a rapidly-growing technology encompassing a large variety of applications including automotive, telecommunications, computers and alternative-energy systems.

While the origin of modem power electronics was stimulated by the development of power semiconductor devices for high frequency switching purposes, other important and necessary accompanying component have been magnetic cores for transformers and inductors.

This need has been especially true for the square wave features produced by solid-state switches that yield a plethora of higher harmonics.

The heart of the new circuitry was the switched mode power supply (SMPS). As this new technology developed, there was an increased demand for miniaturization.

Magnetic cores were traditionally the largest component in a solidstate circuit. Operation at higher frequencies was seen as a possible solution, As power semiconductors were designed for higher frequencies, the magnetic component suppliers were able to develop new materials and shapes that were optimized for the new conditions.

Ferrites were found to be the most suitable materials for the low to medium wattage power supplies. In my flTst book, Modem Ferrite Technology, I said that “ferrites were the new kids on the block”.

While ferrites still maintain their dominance as power magnetic materials, “there are newer kids on the block “, namely amorphous and nanocrystalline materials.

Although these materials are still in their infancy, they require more than a glancing look.
