Abstract
A system for supplying direct current and DC voltage is provided. The system comprise a first supply branch having a first DC voltage source and a power field-effect transistor of a current limiter which are connected in series, and a second supply branch having a second DC voltage source. The power transistor has a current/voltage characteristic with a first inverse polarization area without current limitation, and a second conduction area with current limitation based on a current threshold. The power field-effect transistor is connected to the first voltage source with an inverse polarization when the voltage source of the first branch is operating normally.
