wire for high current inductor

But that is the very least of your problems.

Do you care about the Q of the coil? And if so at what frequency? Or is this just DC. (Oh, air coil or will there be magnetic material involved?)

Firstly, thanks for your suggestions George. I don't have any ideas about the Q factor but it would carry dc current with high frequency switching of

About Phllip's comment, I didn't find enameled copper for such high current available from Farnel or RS.

For what you are now describing, as many as 10 twisted strands might be advantageous.

BTW:

Look into the use of powdered iron cores.

Big ones.

Hi Budiyanto, I haven't made any suggestions, Just trying to understand what you want. I like Phil's idea of using several stands of magnet wire.

I've made a bunch of air core coils but don't know much about magnetic materials.

At 10kHz a 1mH inductor has an impedance of about 50 ohms... at 30 Amps that's a voltage of 1.5 kV! Is that right? This sounds like some very serious power engineering. (Which is way out of my league.)
