A method for starting up a direct electric power supply system for at least two loads, the system comprising an alternating electric power circulation bus, at least one converter for converting alternating power into direct power, at least two connection interfaces being connected to a corresponding converter and being adapted to be connected to at least one electric load to supply direct power to the or each corresponding load, the method comprising the following steps:
- starting the circulation of the alternating electric power in the circulation bus;
- time-shifting the startup moment of the direct power supply from one interface to the other, the shift being controlled by control means.
