Description
CIRCUIT D'ALIMENTATION ADAPTATIF. ADAPTIVE SUPPLY CIRCUIT.
La présente invention concerne un convertisseur courant alternatif - courant continu susceptible d'être connecté sur un réseau polyphasé comportant plusieurs conducteurs de phase et un conducteur de neutre, ce convertisseur comprenant une capacité dont chacune des deux bornes est reliée à chacun des conducteurs de phase par des composants semi-conducteurs présentant un sens de conduction privilégié, tous les composants reliés à une même borne étant branchés dans le même sens et les composants reliés à deux bornes différentes étant branchés en sens contraire.The present invention relates to an alternating current - direct current converter capable of being connected to a polyphase network comprising several phase conductors and a neutral conductor, this converter comprising a capacitance each of whose two terminals is connected to each of the phase conductors by semiconductor components having a preferred direction of conduction, all the components connected to the same terminal being connected in the same direction and the components connected to two different terminals being connected in the opposite direction.
Les convertisseurs de ce type, généralement utilisés comme circuits d'alimentation, sont le plus souvent conçus à partir d'un pont redresseur à diodes, recevant sur son entrée une tension bipolaire et produisant à sa sortie une tension monopolaire appliquée aux bornes d'une capacité dont la fonction est d'assurer un stockage d'énergie et de permettre un filtrage passe-bas de la tension monopolaire.Converters of this type, generally used as supply circuits, are most often designed from a diode rectifier bridge, receiving a bipolar voltage at its input and producing at its output a monopolar voltage applied to the terminals of a capacity whose function is to provide energy storage and to allow low-pass filtering of the monopolar voltage.
Une réalisation de ce type est par exemple illustrée par la figure 3 du brevet européen n 0 034 963 qui représente un convertisseur branché sur un réseau triphasé disposant d'un conducteur de neutre; la capacité est reliée directement, par une de ses bornes, au conducteur neutre, et la tension de sortie du pont redresseur est établie entre le conducteur de neutre et un conducteur supplémentaire relié à l'autre borne de la capacité.An embodiment of this type is for example illustrated by FIG. 3 of European patent n 0 034 963 which represents a converter connected to a three-phase network having a neutral conductor; the capacitor is connected directly, by one of its terminals, to the neutral conductor, and the output voltage of the rectifier bridge is established between the neutral conductor and an additional conductor connected to the other terminal of the capacitor.
Dans les cas où deux au moins des trois phases sont actives, le pont redresseur fonctionne en double alternance, et la tension à la sortie de ce pont est relativement aisée à filtrer. In cases where at least two of the three phases are active, the rectifier bridge operates in full alternation, and the voltage at the output of this bridge is relatively easy to filter.
Dans le cas cependant où seuls le neutre et une phase sont actifs, le pont n'assure plus qu'un redressement simple alternance, et cette tension de sortie ne peut être stabilisée sans l'utilisation d'un filtre extrêmement performant.In the case, however, where only the neutral and one phase are active, the bridge only provides single-wave rectification, and this output voltage cannot be stabilized without the use of an extremely efficient filter.
Dans ce contexte, le but de la présente invention est de proposer des moyens relativement simples et peu coûteux pour permettre la production d'une tension stable même dans le cas où une phase seulement du réseau est active.In this context, the object of the present invention is to propose relatively simple and inexpensive means to allow the production of a stable voltage even in the case where only one phase of the network is active.
A cette fin, le convertisseur de la présente invention est essentiellement caractérisé en ce que chaque borne de la capacité est non seulement reliée à chacune des phases, mais aussi au conducteur neutre par un composant semi-conducteur du même type et de même sens de conduction que les autres, et en ce que ce convertisseur comporte par ailleurs un régulateur de puissance à découpage branché aux bornes de ladite capacité.To this end, the converter of the present invention is essentially characterized in that each terminal of the capacitance is not only connected to each of the phases, but also to the neutral conductor by a semiconductor component of the same type and with the same direction of conduction. than the others, and in that this converter also includes a switching power regulator connected to the terminals of said capacity.
D'autres caractéristiques de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence au dessin annexé dont l'unique figure est un schéma électrique d'un mode de réalisation du convertisseur de l'invention.Other characteristics of the invention will emerge clearly from the description which is given below, for information and in no way limitative, with reference to the appended drawing, the sole figure of which is an electrical diagram of an embodiment of the converter. of the invention.
Comme le montre cette figure, le convertisseur de l'invention, destiné par exemple à fournir une puissance continue sous une tension stable à partir d'une tension alternative de l'ordre de 230 volts, est branché sur un réseau polyphasé doté d'un conducteur de neutre N, le réseau illustré comprenant trois conducteurs de phase, P1, P2, et
P3.As this figure shows, the converter of the invention, intended for example to supply direct power under a stable voltage from an alternating voltage of the order of 230 volts, is connected to a polyphase network provided with a neutral conductor N, the network illustrated comprising three phase conductors, P1, P2, and
P3.
Ce convertisseur comprend une capacité C, indifféremment composée d'un ou plusieurs condensateurs, et dont chacune des deux bornes Ce et Cs est reliée à chacun des conducteurs de phase P1, P2, et P3, ainsi qu'au conducteur de neutre N, par des composants semi-conducteurs D1, D2, D3, D4, D5, D6, D7, et D8 présentant chacun un sens de conduction privilégié.This converter includes a capacitor C, indifferently composed of one or more capacitors, and each of the two terminals Ce and Cs of which is connected to each of the phase conductors P1, P2, and P3, as well as to the neutral conductor N, by semiconductor components D1, D2, D3, D4, D5, D6, D7, and D8 each having a preferred direction of conduction.
Ces composants, par exemple constitués de diodes dont l'emploi est bien connu dans l'art antérieur pour ce type d'application, sont montés en pont redresseur double alternance, c'est-à-dire que tous les composants (D1 à D4 d'une part et D5 à D8 d'autre part) qui sont reliés à une même borne de la capacité C (Ce d'une part et Cs d'autre part) sont branchés dans le même sens alors que les composants reliés à deux bornes différentes, tels que D1 et
D5 par exemple, sont branchés en sens contraire.These components, for example consisting of diodes, the use of which is well known in the prior art for this type of application, are mounted as a full-wave rectifier bridge, that is to say that all of the components (D1 to D4 on the one hand and D5 to D8 on the other hand) which are connected to the same terminal of capacitance C (Ce on the one hand and Cs on the other hand) are connected in the same direction while the components connected to two different terminals, such as D1 and
D5 for example, are connected in the opposite direction.
Enfin, en plus du pont redresseur D1 à D8 et de la capacité
C, le convertisseur de l'invention comporte un régulateur de puissance à découpage R branché aux bornes Ce et Cs de la capacité C et délivrant entre ses deux bornes de sortie RI et
R2 un courant constant sous une tension V continue et régulée.Finally, in addition to the rectifier bridge D1 to D8 and the capacity
C, the converter of the invention comprises a switching power regulator R connected to the terminals Ce and Cs of the capacitor C and delivering between its two output terminals RI and
R2 a constant current under a continuous and regulated voltage V.
Le régulateur R, qui a pour fonction d'une part de lisser les ondulations de la tension monopolaire disponible aux bornes de la capacité C et d'autre part de compenser les variations d'amplitude crête de cette tension monopolaire, peut être constitué de tout circuit approprié disponible dans l'art antérieur, et par exemple du circuit intégré du type Si9100 fabriqué par la société Siliconix Incorporated.The regulator R, which has the function on the one hand of smoothing the ripples of the monopolar voltage available at the terminals of the capacitor C and on the other hand of compensating the variations of peak amplitude of this monopolar voltage, can be made up of any suitable circuit available in the prior art, and for example of the Si9100 type integrated circuit manufactured by the company Siliconix Incorporated.
En dépit de sa structure extrêmement simple, le convertisseur de l'invention délivre une tension V continue et d'amplitude au moins approximativement constante dans tous les cas où au moins deux quelconques des conducteurs N, P1, P2, et P3 sont branchés et portés à leur potentiel de service. Despite its extremely simple structure, the converter of the invention delivers a DC voltage of at least approximately constant amplitude in all cases where at least any two of the conductors N, P1, P2, and P3 are connected and carried to their service potential.
