Frederik Dostal, Analog Devices

For many years, engineers have used calculation tools to optimize a switch mode power supply design. In the early years, power supply engineers would program their own tools or use spreadsheets they generated themselves with the required formulas underlying a certain power supply topology. While this helped tr

Real-world magnetics design

Dr. Ray Ridley, Ridley Engineering

Proper design of magnetics components is at the heart of any power converter. In this article, the flaws of some production magnetics are shown, clearly showing why it is essential that designers of power supplies should be intimately involved in magnetics design and characterization. Teaching power magnetics d
