Hello,
We are doing a 3kw Grid tied inverter. We need a 1mH inductor capable of carrying 25 Amps peak, and with 13 Amps RMS. Switching frequency is 17khz
(as per app note on page 23)…

We went through all the powder core torroids on mag-inc.com and they all need too many turns and are too physically big.
Do you know of a core material we can use with this and get a smaller inductor?
