SYSTEM AND METHOD OF SUPPLYING AN ELECTRICAL SYSTEM WITH DIRECT CURRENT
First Claim
1. A system for supplying an electrical system with direct current, comprisingat least two direct current power supply devices, each comprising means of electrical connection to an alternating current source and an AC/DC converter of alternating current into direct current, a module for managing the power supply of the electrical system configured, after reception of an information of failure of a first active power supply device, to transmit a command to start up a second inactive power supply device, and a back up electrical energy storage device electrically by-pass connected between the supply devices and the electrical system,wherein the management module is configured to receive the information of failure from the back up device or from the electrical system, or both, and to transmit the command to start up the second power supply device during a discharge phase of the back up device.

Abstract
A system for supplying an electrical system with direct current, the system including at least two direct current power supply devices each having means of electrical connection to an alternating current power supply source and an AC/DC converter of alternating current into direct current, a module for managing the power supply of the electrical system which, after reception of an information of failure of a first active power supply device, transmits a command to start up a second inactive power supply device and a back up electrical energy storage device electrically by-pass connected between the power supply devices and the electrical system. The management module also receives the information of failure from the back up device and/or from the electrical system and transmits the command to start up the second power supply device during a discharge phase of the back up device.

7. A method for supplying an electrical system with direct current, comprising:
-
providing at least two direct current power supply devices, each comprising means of electrical connection to an alternating current source; and
an AC/DC converter of alternating current into direct current;receiving, by a module for managing the power supply of the electrical system, an information of failure of a first active power supply device; transmit a command to start up a second inactive power supply device, and of a back up electrical energy storage device electrically by-pass connected between the supply devices and the electrical system, receiving, by said management module, the information of failure from the back up device or from the electrical system, or both the command to start up the second power supply device is transmitted by the management module during a discharge phase of the back up device. - View Dependent Claims (8, 9, 10, 11)
