Beschreibung
Zusammenfassung:	The invention concerns an electrical system that comprises: -an electrical charge (42, 43); -a decoupling capacitor (41); -a DC voltage power supply system, comprising first and second terminals (321, 322), including: -a DC voltage source (2) comprising first and second poles; -a first branch including a first contactor (51); -a second branch including first and second switches (302, 303) and an inductor (305) connected in series in order to selectively connect the DC voltage source to the first terminal (321) of the power supply system; -a unidirectional conducting device (307, 308, 309) for conduction from the second terminal of the DC power supply system to a connection node (323) between the second switch (303) and said inductor (305); -a control circuit (304) comprising -a mode for supplying electrical load (42, 43); -a mode for charging the decoupling capacitor (41).
