Hello all,
I'm building an 8-10Kw 48V inverter. The inverter etc I can make, but I've been unable to find a suitable source of cores. The Asian manufacturers will ship them if you want a minimum of 10 units. Is there an Australian manufacturer who has cores I could stack for more power, or just has that kind of item without making a one-off?
Is there a large toroid used in some piece of equipment that I could strip down & stack for a new core?
I'd like a larger inner diameter to accommodate easier winding. I may wrap the primary as multiple large enamelled winding wire inside fibreglass woven cloth tubing rather than PVC insulated regular cable. Better cooling. The whole core will be carefully supported and forced air cooled.
My minimum load power is about 300 watts.
Average load is about 1000 watts.
High load is 7500 watts for a few hours.
There will be an EV slurping up more power at a later date.
Also, this will not be a budget build, so spending money on a quality core that lasts forever is where I stand.
Much appreciated,
