Variable switching power supply.
La présente invention concerne tous les appareils utilisant des résistances ou matériaux similaires pour transformer l'énergie en chaleur ou en froid et pour lesquels il n'est pas indispensable d'avoir un maximum de puissance immédiate. The present invention relates to all devices using resistors or similar materials to transform energy into heat or cold and for which it is not essential to have a maximum of immediate power.
Des dispositifs similaires Je peux citer le système d'alimentation programmable bien que ce dernier soit différent quant aux résultats ; d'autre part il peut être couplé avec le mien. Similar devices I can cite the programmable power system although the latter is different in terms of results; on the other hand it can be coupled with mine.
Suivant mon invention par un dispositif d'alimentation à commutation variable (de 1 Hz à 30 Hz), j'alimente un groupe de résistances (2 à X) les unes après les autres à une vitesse de commutation variable, cette vitesse variable permettant d'agir directement sur la dissipation de calories que lton souhaite. According to my invention by a variable switching power supply device (from 1 Hz to 30 Hz), I feed a group of resistors (2 to X) one after the other at a variable switching speed, this variable speed allowing d '' Act directly on the dissipation of calories that you want.
Le fait d'alimenter ces résistances les unes après les autres offre l'avantage de diminuer considérablement la puissance d'alimentation à la source. Si la perte en calories est d'environ de 8% par contre l'économie réalisée en énergie est d'environ 35%, ce qui se traduit en faisant le rapport calorie-température par une économie de 27% et une absence totale de surcharge en intensité. Basée sur le principe du temps que met une résistance pour atteindre une température x et le temps que met cette même résistance pour revenir à sa température initiale (temps x fois supérieur), mon invention permet donc de faire travailler chaque résistance au seuil de sa température d'équilibre.The fact of supplying these resistors one after the other has the advantage of considerably reducing the power supply at the source. If the calorie loss is around 8%, on the other hand, the energy saving is around 35%, which results in the calorie-temperature ratio by a saving of 27% and a total absence of overload. in intensity. Based on the principle of the time that a resistance takes to reach a temperature x and the time that this same resistance takes to return to its initial temperature (time x times higher), my invention therefore allows each resistance to work at the threshold of its temperature of balance.
Le dessin annexe schéma synoptique FIG.1 est un simple montage électronique donné à titre d'exemple et appliqué à un cas de multiplexage à quatre voix. The annexed diagram block diagram FIG.1 is a simple electronic assembly given by way of example and applied to a case of multiplexing with four voices.
Tout système de multiplexage est valable quant au nombre de voix ; il ne peut être déterminé qu'en fonction de l'utilisation à laquelle mon système doit entre appliqué.Any multiplexing system is valid as regards the number of votes; it can only be determined based on the use to which my system must be applied.
IC1 est un oscillateur variable, réglage fait par R1 qui donne la pulsation quant au démarrage. Ces pulsations sont transmises à IC2 ; celui-ci est un registre à décalage avec 4 sorties qui sont basculées par les quatre portes
conduire de IC3, ce dernier ne délivrant pas assez de courant pour\ directement les triacs, il y a pour cela quatre transistors (TR 5.6.7.8) qui attaquent les gachettes des triacs TR 9.10.11.12. Ce système est alimenté par une alimentation de 6 volts (Ai). Le contrôle automatique de température des résistances est réalisé par un détecteur thermique inséré dans un pont qui monté à la place de R1 fera varier l'oscillateur en fonction de la température sélectionnée.IC1 is a variable oscillator, adjustment made by R1 which gives the pulsation as for starting. These pulses are transmitted to IC2; this is a shift register with 4 outputs that are toggled by the four doors
drive from IC3, the latter not delivering enough current to \ directly the triacs, for this there are four transistors (TR 5.6.7.8) which attack the triggers of the triacs TR 9.10.11.12. This system is powered by a 6 volt (Ai) power supply. The automatic temperature control of the resistors is carried out by a thermal detector inserted in a bridge which mounted in place of R1 will vary the oscillator according to the selected temperature.
Ce système peut être utilisé pour tous les dispositifs générateurs de calories quels qu'ils soient, aussi bien dans l'industrie, l'agriculture que dans les utilisations domestiques, chaque fois que la notion de maximum d'énergie immédiate n'est pas requise. En résumé, il se caractérise par son économie d'énergie, sa facilité d'exploitation, sa fiabilité et sa réduction d'intensité immédiate. This system can be used for all calorie-generating devices of any kind, whether in industry, agriculture or in domestic uses, whenever the notion of maximum immediate energy is not required . In summary, it is characterized by its energy saving, its ease of operation, its reliability and its reduction in immediate intensity.
Le synoptique FIG.2 correspond à un
système asservissant le chauffage d'un local de quatre pièces.The diagram FIG. 2 corresponds to a
system controlling the heating of a room with four rooms.
I1 comprend une unité de commande composée d'une alimentation basse tension (17), d'un oscillateur (15). Cet oscillateur est commandé par un capteur thermique (16) qui en fonction de la température ambiante fera varier la vitesse de commutation. L'oscillateur (15) commande un registre à décalage (14), ce dernier est basculé par le circuit (13) et amplifié par les transistors (9-10-11-12) qui attaquent les gachettes des triacs (5-6-7-8) ; en 1-2-3-4 se trouvent les quatre radiateurs. Ce mode d'alimentation offre une très bonne répartition de chaleur tout en diminuant la dépense d'énergie et la surcharge en intensité, ce qui dans le cas d'utilisation domestique, permet d'avoir une réduction de contrat E.D.F. I1 comprises a control unit composed of a low voltage supply (17), an oscillator (15). This oscillator is controlled by a thermal sensor (16) which, depending on the ambient temperature, will vary the switching speed. The oscillator (15) controls a shift register (14), the latter is tilted by the circuit (13) and amplified by the transistors (9-10-11-12) which attack the triggers of the triacs (5-6- 7-8); in 1-2-3-4 are the four radiators. This mode of supply offers a very good distribution of heat while reducing the energy expenditure and the overload in intensity, which in the case of domestic use, allows to have a reduction of contract E.D.F.
