3/28/2023 0 Comments Ferrite inductor calculatorsince I can't obtain the required inductors. Which is why you'll only ever see enamel covered wire used in commercial PSUs. Plastic insulation melts quite easily: that leads to shorts and more heating, and you have a runaway thermal situation pretty quickly. That means there's a fair bit of peak heating. There's a fair bit of peak current through your inductor. Would using multi-stranded plastic-insulated wire be a good idea? You can use a modelling tool to get a ballpark. But in the real world they only ever give you guidelines: the exact core material will vary, as will your turn spacing, air gapping, atmospheric moisture content, etc. There isn't a single 'formula', but those models are using some pretty well tested maths. There are models, and some useful tools for some ferrite/powdered iron cores. Is there a formula for saturation current?
