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.
