How did you get those values?For 48volt 50 Amp system (50Hz) the choke would be 3.072 mH at 80 Amps saturation, which would measure as about 3.74 mH with zero dc.
Output filter capacitor would be 20,000uF
Its tied up with the requirement for <5% ripple which is a typical specification for commercial transformer/rectifier battery chargers.How did you get those values?
That is exactly the situation.You will require custom transformers and chokes. The transformer I believe would weight on its own over 25 kilograms.
The DC choke it will be even larger; I have a 2.5 joule one (made by Hammond mfg.) which weighs 7 kilograms. You require 19.5 joule one which will be over 50 kilograms.
At the current cost of copper and magnetic grade steel, these two components alone will be well over $1200 US.
