Electrical assembly and method for supplying without interruption an installation with alternating current
First Claim
1. An electrical assembly comprising an installation comprising an alternating current power supply port and at least one electrical system, and an uninterruptible power supply device for supplying without interruption with alternating current the power supply port, the uninterruptible power supply device comprising:
- a first circuit for electrically connecting the alternating current power supply port of the installation to an alternating current power supply network; and
a back up device comprising a rectifier, means for charging, means for storing and means for electrical energy, and an inverter connectable to the alternating current power supply port of the installation,wherein the back up device is arranged in a second alternating current supply circuit connectable to the alternating current power supply port in a by-pass of the first circuit,wherein the uninterruptible power supply device comprises a switch arranged and commanded to connect selectively the first or the second circuit to the alternating current power supply port as a function of a state of the power supply of the electrical system in the installation,wherein each electrical system of the installation consumes direct current and is electrically connected to the alternating current power supply port through a direct current power supply device with AC/DC conversion,wherein the switch is commanded to connect selectively the first or the second circuit to the alternating current power supply port as a function of a state of the supply with direct current of the electrical system in the installation, andwherein the installation further comprises at least one module for managing the power supply of the electrical system designed to transmit an information message on the state of the direct current power supply of the electrical system to a controller of the switch, said controller being located upstream of said AC/DC conversion.

Abstract
An electrical assembly including an installation having an alternating current power supply port and at least one electrical system, and a device for supplying without interruption with alternating current the power supply port. The uninterruptible power supply device includes a first circuit for electrically connecting the power supply port to an alternating current power supply network, and a back up device including a rectifier, means for charging, storing and discharging electrical energy, and an inverter, connectable to the power supply port. The back up device is arranged in a second alternating current power supply circuit connectable to the power supply port in a by-pass of the first circuit. The uninterruptible power supply device includes a switch to connect selectively the first or the second circuit to the power supply port as a function of a state of the power supply of the electrical system in the installation.

8. A method of supplying without interruption an electrical supply port of an installation with alternating current comprising at least one electrical system connected to the power supply port, comprising the steps of:
-
supplying the installation with alternating current by default using a first circuit which electrically connects the electrical power supply port to an alternating current power supply network; supplying the installation with alternating current using a back up device comprising a rectifier, means for charging, means for storing and means for discharging electrical energy, and an inverter electrically arranged between the alternating current power supply network and the power supply port of the installation in the event of malfunction of the power supply by default, wherein the back up device is arranged in a second alternating current power supply circuit connected to the power supply port in a by-pass of the first circuit, wherein the method further comprises a step of commutation by a switch between a power supply by the first or the second circuit as a function of a state of the power supply of the electrical system in the installation, each electrical system consuming direct current and being electrically connected to the power supply port through a direct current power supply device with AC/DC conversion, wherein the method further comprises a step of transmitting, by a management module of the installation, an information message on the state of a direct current power supply of the electrical system to a controller of the switch, said controller being located upstream of said AC/DC conversion, and wherein the state of power supply of the electrical system in the installation is the state of direct current power supply of the electrical system in the installation.
