I'm designing a DC-DC Flyback or SEPIC converter, not decided yet.
The converter is used to source some power LED's. The output voltage up to 60V and 1A with an input of 12-24V. The switching frequency should be between 100kHz and 1MHz, because of the switching losses, we are considering a rather low frequency.
So I just had a glance what type of coupled inductors may be avaiable on the market.
I looked first for an inductor with ~40uH series inductance at a current raiting above 5A and an even higher satturation current.
But I could just find some rather strange products, looking like ment for a rather specific application.
Are there other more common terms than "coupled inductor" to find such products? Also manufacturer names would be helpful.
I know a transformer may met my conditions, but are transformers not by general ment to transform energy rather than store it?
