This datasheet shows a couple of typical inductance vs frequency charts:

Over the non-saturated, nearly linear regions, inductance is slightly inversely proportional to frequency.

Self-heating will change inductance a little, numbers like 100 PPM/K.
Here's part of what I'm doing.

We're designing a couple of products (one dummy load, one power supply, both 8 isolated channels) and each board needs 8 isolated
20-watt power supplies. So we have 8 full bridges each pumping a 500 KHz square wave into a transformer-rectifier.All share the +48 supply. If we polyphase the square wave drives, the ripple currents will kinda cancel and the channels all share their
2.2u caps. I think.Join the Discussion
