There are several articles about how to turn a DC voltage source into a DC current source but what about the opposite?
The real situation is a "black box" current source capable of supplying 0.5 A DC current when connected to a 1K Ohm external power resistance.
Connecting two black boxes in parallel results in a doubling of the current value.
The open-circuit DC voltage is practically zero.
What is the best principal/practical way to convert this current source into a practical voltage supply ( high voltage DC or rather ultimately 110/220V AC ) without any modification of the black box?
What is then the best possible conversion efficiency?
