I have a boost converter that will convert 12V and 11A to around 20V and 6A. Since I didn't find any inductors (in my local stores) capable of such currents and frequencies and the correct inductance I decided to build one myself.
I've calculated the required inductances to be around 3uH for 11A and a couple of 710uH (for a low pass filters in 'boosted' section) for 6A, but am having doubts about saturation current.
I've seen an anwser on this site showing how to measure it, but I would like to calculate it prior to actually winding them.
I've seen some ferrite cores with 'air gapes' to achieve high saturation currents, I've seen toroidal and cylindrical cores with and without those air gaps. But I havent seen any specific numbers in their datasheets about the saturation current. So I am completely lost here…
So is saturation current dependent on core material/type/dimensions? If I know these values how can I calculate it?
