A Guide To Automating Layout Of Planar Magnetic Designs

Focus:
Though planar magnetics have been around for years, the task of routing the windings for a planar magnetic component has largely remained a manual and tedious task. In addition to being time consuming, manual routing also entails a barrier to minor adjustments and improvements, as even minor changes imply a large or complete redesign of the PCB. To overcome these problems, the author developed a free online tool called AutoPlanar, which automates the process of laying out windings for a planar transformer or inductor. In this 17-page article, the author explains the design rules governing AutoPlanar’s operation, and walks the reader through the process of laying out a planar magnetic component using the tool’s PCB Wizard and how to create a new design or edit an existing one using the tool’s PCB Advanced Creator, the feature for advanced users.
