3x fixed ration voltage boost is from 3 phase 480AC to 831DC is currently less than $100 in parts with modern electronics.
480/sqrt(3) = 277
277 * 3 = 831
I don't know why they make a big deal out of it.
- SigmundA 5y agoReally a $100 for 900 amp input 450 amp output boost DC power supply?
- baybal2 5y agoThe magic of silicon carbide. Remember, having a 3 phase input means you have 1/3 the current per phase Though, I will concede on the price estimate. At 250kw, you get 180A per phase, which is still outside of range for commodity parts. And at 350kw, switches which can handle 250A cost few hundred dollars each. Alternatively, you can use a 3 phase transformer to 1400V, and rectify to 800DC.
