Abstract

The subject of the invention is a backup supply device termed an inverter. According to the invention, an inverter 3 incorporates means enabling the mixing of two distinct AC voltages of like frequency and like phase, on the one hand from a network to be backed up, termed the mains network 1, and on the other hand, an AC independent network 11, so as to distribute it to the traversed network 4; resulting mainly in an amplitude-regulated AC voltage of the backed-up network, without voltage interruption or jump which may be prejudicial to the operation of the said backed-up network. Application to the supply of computer processing apparatus.

Description

La presente invention concerne un dispositif permettant le mélange de deux tensions alternatives provenant de deux réseaux distincts. The present invention relates to a device for mixing two alternating voltages from two separate networks.

Le but de l'invention est de substituer à un réseau alternatif défaillant un réseau alternatif autcr nome, sans commutation d'un réseau à l'autre pendant ladite substitution. The object of the invention is to substitute for a failing alternative network an alternative alternative network, without switching from one network to another during said substitution.

Selon l'invention, le dispositif permet le mélange en phase, de deux tensions alternatives de même fréquence, d'amplitudes différentes ou égales et d'obtenir une tension alternative quasi-constante. According to the invention, the device allows the mixing in phase of two alternating voltages of the same frequency, of different or equal amplitudes and of obtaining a quasi-constant alternating voltage.

Lorsque le réseau à secourir n'est pas défaillant, le dispositif mélangeur autorise le passage du réseau à secourir tout en interdisant le passage du réseau autonome. Inversement, lorsque le réseau à secourir est défaillant, le réseau autonome prend la place du réseau à secourir d'une façon continue, sans commutation ni interruption. When the network to be rescued is not faulty, the mixing device authorizes the passage of the network to be rescued while preventing the passage of the autonomous network. Conversely, when the network to be rescued fails, the autonomous network takes the place of the network to be rescued continuously, without switching or interruption.

Le dispositif melangeur est commandé par une centrale logique de décision qui interrompt le passage du réseau à secourir au dispositif mélangeur quand le réseau autonome n'est plus en phase avec le reseau à secourir. La logique de décision autorise à nouveau le passage du réseau à secourir au dispositif mélangeur quand ces deux réseaux sont en phase. The mixing device is controlled by a logic central decision which interrupts the passage of the network to be rescued to the mixing device when the autonomous network is no longer in phase with the network to be rescued. The decision logic again authorizes the passage of the network to rescue the mixing device when these two networks are in phase.

Selon l'invention, un générateur d'alimentation en courant alternatif, destiné à se substituer à un circuit normal d'alimentation, tel que le secteur, pour alimenter un circuit dit secouru, ledit générateur comprenant une batterie d'accumulateur et un convertisseur dit onduleur est connecté au circuit dit secouru par l'intermediaire d'un dispositif mélangeur, ledit dispositif étant lui-même connecté au circuit normal d'alimentation. According to the invention, an alternating current supply generator, intended to replace a normal supply circuit, such as the mains, for supplying a so-called back-up circuit, said generator comprising a storage battery and a so-called converter the inverter is connected to the so-called back-up circuit via a mixing device, said device itself being connected to the normal supply circuit.

Le dispositif mélangeur incorpore des semi-conducteurs tels que diodes, des commutateurs électroniques tels que tyristors, triacs , sous la dépendance d'ure centrale logique de décision qui elle-même est sous la dé pendance dudit secteur et du réseau autonome. The mixing device incorporates semiconductors such as diodes, electronic switches such as tyristors, triacs, under the dependence of a logic decision-making central unit which itself is under the dependence of said sector and of the autonomous network.

Les avantages et autres caractéristiques de l'invention apparaîtront au cours de la description qui va suivre. Le dessin annexé est donné uniquement à titre d'exemple. The advantages and other characteristics of the invention will become apparent from the description which follows. The accompanying drawing is given by way of example only.

En se référant à la fig.l l'on voit le réseau à secourir l alimenter le transformateur 2 et le réseau secouru 4 via le dispositif mélangeur 3. Ledit transformateur par un enroulement auxiliaire 5 maintient en char ge, par un dispositif de charge 6, la batterie d'accumulateur 7. Referring to fig. L we see the network to be supplied by the transformer 2 and the network backed up 4 by the mixing device 3. Said transformer by an auxiliary winding 5 keeps in charge by a charging device 6 , the storage battery 7.

Lors d'une défaillance du réseau à secourir l le dispositif mélangeur 3, recevant le réseau à secourir aux entrées 9 et 10, laisse passer le réseau autonome il aux entrées 12 et 13 jusqu'aux sorties 14 et 15 du dispositif 3, sorties connectées au réseau secouru 4. Il découle de cette conception un fonctionnement stable du réseau secouru, dans coupures ni sauts de tensions préjudicia bles au réseau secouru. Ledit réseau recevant soit le réseau à secourir, soit le réseau autonome, si une baisse de tension non préjudiciable au réseau secouru apparaît au réseau à secourir. In the event of a failure of the network to be rescued l the mixing device 3, receiving the network to be rescued at inputs 9 and 10, lets the autonomous network pass through it at inputs 12 and 13 to outputs 14 and 15 of device 3, connected outputs to the backed-up network 4. From this design results a stable operation of the backed-up network, in cuts or jumps of voltages detrimental to the backed-up network. Said network receiving either the network to be assisted, or the autonomous network, if a drop in voltage not detrimental to the network assisted appears to the network to be assisted.

Une surtension du réseau à secourir préjudiciable au réseau secouru est éliminée par la présence du transformateur 2 et l'enroulement 5. En effet au moment de la surtension, la logique de décision 8 autorise la charge des batteries par l'intermédiaire du chargeur 6. Par conséquent, la surtension préjudiciable ne peut apparaître aux bornes du transformateur 2 qui lui-même ne peut perturber le réseau secouru 4. An overvoltage in the back-up network detrimental to the back-up network is eliminated by the presence of the transformer 2 and the winding 5. In fact at the time of the overvoltage, the decision logic 8 authorizes the charging of the batteries via the charger 6. Consequently, the damaging overvoltage cannot appear at the terminals of the transformer 2 which itself cannot disturb the backed-up network 4.

Les avantages de ce type de fonctionnement sont, d'une part, une plus grande simplicité dans la conception d'une alimentation autonome d'énergie, et d'autre part, l'alimentation autonome ne délivrant de l'énergie puisée dans les accumulateurs seulement quand une défaillan ce du réseau secteur apparat, une plus grande fiabilité et un échauffement de l'alimentation autonome très réduit. Il en résulte un fonctionnement en "veille" du réseau autonome quasi-continu. The advantages of this type of operation are, on the one hand, greater simplicity in the design of an autonomous power supply, and on the other hand, the autonomous power supply does not deliver energy drawn from the accumulators only when a failure of the mains network appears, greater reliability and very low heating of the autonomous power supply. This results in a standby operation of the quasi-continuous autonomous network.

Il existe des applications de l'invention dont l'une est la conception d'un onduleur adapté au marché de l'informatique.  There are applications of the invention, one of which is the design of an inverter suitable for the computer market.
