Transformer Design (Part 2): Aspect Ratio

by Dennis Feucht, Innovatia Laboratories, Cayo, Belize, How2Power Today, Feb 16 2018

Focus:
This discussion on core utilization in transformer design continues with a study of aspect ratio. For transformer high-current primary windings, the aspect ratio of the transformer winding window is an important constraint in winding design. Here in part 2, we present an example (the transformer design for a boost push-pull battery converter) that demonstrates how aspect ratio constrains a full winding window and how it affects power transfer. This example serves as a design template for readers looking to perform similar transformer design optimizations. This example also demonstrates how aspect ratio can affect eddy-current losses. A table lists aspect ratios for different cores. The impact of twisted wire bundles on eddy- current effects is briefly discussed.
