Focus:
Although the design of magnetic cores is usually left to magnetics manufacturers, having some insight into why cores have particular geometric parameters can aid power supply engineers in transductor design. This article explains why core geometries dictate tradeoffs in various core parameters and in figures of merit such as maximum power-transfer utilization and windability, which will give designers a better handle on how to optimize core selection. Furthermore, it will give designers some insights into the impact of shrinking core sizes on these tradeoffs.

What you’ll learn:

• How to understand the role of core geometry in tradeoffs of various core parameters and figures of merit for transformers and coupled inductors
