System for supplying DC power to at least two loads from an AC power source and method for starting such a power supply system

The power supply system (10) has circulation bus (14) for alternating power adapted to be connected to alternating power source (12), converters (16) connected to circulation bus to convert alternating power into direct power, connection interfaces (20A-20E)connected to converters and adapted to be connected to electric loads (22) to supply direct electric power to loads, and control unit which controls connection interfaces, and capable of time-shifting start-up moment for supply of direct power from one interface to other. An independent claim is also included for a method for starting up direct electric power supply system or two loads.
