Capacitance and capacitors rating
I started looking into different designs of induction heaters and it seems that for powerful heaters like >=10kW people at least a few µF with a few hundred amps rating capacitors. What's a minimum for ReactorForge?
And regarding manufacturers, it seems most people use Celems, but I've seen Chinese water cooled capacitors as well, for example on AliExpress: https://www.aliexpress.com/af/water-cooled-capacitor.html?SearchText=water+cooled+capacitor&d=y&initiative_id=SB_20190114153544&origin=n&catId=0&isViewCP=y&jump=afs Has anyone tried anything other than Celems? Is there a huge difference?
Thanks for a reply!
I was also wondering about frequency rating on these capacitors, but I think I have better understanding of it now. If anyone else is curious - capacitors' ratings change with frequency and maximum current rating will be usually much smaller in a low frequency as compared to a high frequency.
I think that in the end I'll probably start with some chinese stuff for my first induction heater because I wouldn't want to blow up a Celem capacitor with my limited experience and then when I'll be ready to build a more powerful heater, I'll try to get a Celem capacitor. I've seen lots of used capacitors on Ebay, I might give one a try. They're rather rare in Europe, but I usually visit USA at least once in a year, so I'll probably buy something on my next visit.
