Mind The Gap And Improve Your Low-Power Flyback Transformer Design.

The article analyzes several aspects related to the provision of gaps while designing transformers. It is reported that, gaps are left in transformers built on ferrite structures for higher-power storage or for large dc currents. It is reported that, although for low-power and low-current applications flyback transformer using a ferrite core that doesn't have a gap might seem appealing, it will cause poor performance.
