Visualizing Hot Loops and Return Paths to Remove EMI in a Flyback Converter

Published Date

Struggling with EMI issues in your flyback or switch-mode power supply? In this video, Kirsch breaks down why flyback converters often fail EMI testing and, more importantly, how to fix the issue using PCB layout techniques that require no additional components. You’ll learn how hot loops and broken return paths are the primary culprits behind high electromagnetic emissions, and how to minimize them with component placement, copper pours, and return path strategy. With a real-world PCB layout example in Allegro X, this tutorial provides actionable design tips that you can apply immediately to your power converter designs.
