5.1 Flyback transformer design considerations of efficiency and EMI

Three main topology components dominate flyback-converter performance: the primary switch, secondary rectifier and transformer. This training series focuses on the importance of transformer design, since this single component has a profound impact on converter efficiency and electromagnetic interference (EMI). This training series discusses the various conflicting design requirements, the often-neglected subtleties of core loss and snubber clamp level, and ways to improve transformer performance.

Why should I take this training?

• The transformer design of an isolated flyback has a large influence on the overall performance of the supply
• Optimizing materials and winding structure can help improve efficiency and EMI performance 

What will I learn?

• Basics of the flyback transformer
• Review of flyback transformer losses
• Considerations for mitigating EMI by optimizing transformer design
