Description

La présente invention concerne un dispositif électronique comprenant une série de condensateurs de diodes et de commutateurs montes suivant une disposition déterminée, destin à transformer le courant alternatif ou continu en courant continu sous une tension plus basse, à fournir une très forte puissance, et à remplacer avantageusement tout transformateur abaisseur de tension de type ferro-magnétique à bobine.The present invention relates to an electronic device comprising a series of diode capacitors and switches mounted in a determined arrangement, intended to transform alternating or direct current into direct current at a lower voltage, to provide a very high power, and to replace advantageously any step-down transformer of the ferro-magnetic type with coil.

La présente invention est une innovation pressentant des avantages par rapport au transformateur classique à bobine qu'elle devra remplacer vu son poids plus faible, son volume plus réduit, son échauffement négligeable, et ses effets parasites minimes compares au convertisseur à découpage.The present invention is an innovation sensing advantages compared to the conventional coil transformer which it will have to replace given its lower weight, its smaller volume, its negligible heating, and its minimal parasitic effects compared to the switching converter.

La présente invention sera mieux comprise dans son principe en référence à la description des dessins annexés.The present invention will be better understood in principle with reference to the description of the accompanying drawings.

La figure 1 représentant le plus simple dispositif transformant le courant alternatif en courant continu avec abaissement de la tension à la sortie.Figure 1 showing the simplest device transforming alternating current into direct current with lowering of the voltage at the output.

La figure 2 représentant un dispositif double travaillant pendant les 2 alternances du courant alternatif tant au niveau des circuits primaires que secondaires.FIG. 2 representing a double device working during the two half-waves of the alternating current both at the level of the primary and secondary circuits.

La figure 3 représentant un dispositif double mais dont les commutateurs sont de type optoélectronique.FIG. 3 represents a double device but the switches of which are of the optoelectronic type.

Dans la figure 1, pendant la phase (+) positive du courant alternatif à l'entrée :
Dans le circuit primaire (1), les diodes DI et D2 étant dans le sens passant, les condensateurs C1, C2, Cs étant de meme capacité et montés en série avec les diodes dl et d2 ; le courant charge les condensateurs C1, C2, C3, la tension Vc , V , V aux bornes de chaque condensateur est identique et egale i 2 C3 1 au tiers C-) de la tension initiale Ve à l'entree (ou égale à - de la tension
3 n initiale si n condensateurs sont utilisés).In Figure 1, during the positive (+) phase of the alternating current at the input:
In the primary circuit (1), the diodes DI and D2 being in the forward direction, the capacitors C1, C2, Cs being of the same capacity and connected in series with the diodes dl and d2; the current charges the capacitors C1, C2, C3, the voltage Vc, V, V across each capacitor is identical and equal i 2 C3 1 to the third C-) from the initial voltage Ve at the input (or equal to - tension
3 n initial if n capacitors are used).


V = V = V = Ve Dans cet exemple n = 3.
V = V = V = Ve In this example n = 3.

1 C3 Dans
La puissance Pe du courant à l'entrez est égale au produit de la tension Ve à l'entrez par l'intensité Ie à l'entrée : Pe = Ve x Ie.1 C3 In
The power Pe of the current at the input is equal to the product of the voltage Ve at the input by the intensity Ie at the input: Pe = Ve x Ie.

Dans le circuit secondaire (2), les commutateurs K1 et K2 restant ouverts, donc aucun courant ne passe à la sortie et l'isolation galvanique est assurée.In the secondary circuit (2), the switches K1 and K2 remain open, so no current flows at the output and galvanic isolation is ensured.

Pendant la phase (-) négative du courant alternatif à l'entrez
Dans le circuit primaire (1), aucun courant ne traverse le circuit, les diodes
D1 et D2 étant polarises dans le sens inverse, ce qui conduit à l'isolation
galvanique complète. During the negative (-) phase of the alternating current at the start
In the primary circuit (1), no current flows through the circuit, the diodes
D1 and D2 being polarized in the opposite direction, which leads to isolation
full galvanic.

Dans le circuit secondaire (2), les commutateurs K1 et K2 se ferment, les condensateurs C1, C2, C3 de même capacité étant montes en parallèle par la disposition des diodes D3, D4, D5, D6, D7, D7, DS ; les courants il, i2, i3 de même intensité traversant les condensateurs C1, C2, C3 s'ajoutent et l'intensité I finale obtenue à la sortie du commutateur K1 est gale à la
s somme des intensités il, i2, i3 ;Is il + 12 + i3 avec i1 = i2 = i3 3 I
s e donc I = 3 I
s e tandis que la tension V de sortie aux bornes des commutateurs K1 et K2 est
s égale à la tension aux bornes de chaque condensateur C1, C2, C3 et égale au
3 de la tension V e initiale à l'entrée
V V =V =V V V = e
s cl c2 C3 3
Par conséquent la puissante Ps à la sortie est gale au produit de la tension
V à la sortie par l'intensité I à la sortie.In the secondary circuit (2), the switches K1 and K2 close, the capacitors C1, C2, C3 of the same capacity being connected in parallel by the arrangement of the diodes D3, D4, D5, D6, D7, D7, DS; the currents il, i2, i3 of the same intensity passing through the capacitors C1, C2, C3 are added and the final intensity I obtained at the output of the switch K1 is equal to the
s sum of the intensities il, i2, i3; Is il + 12 + i3 with i1 = i2 = i3 3 I
se therefore I = 3 I
while the output voltage V at the terminals of switches K1 and K2 is
s equal to the voltage across each capacitor C1, C2, C3 and equal to
3 of the initial voltage V e at the input
VV = V = VVV = e
s cl c2 C3 3
Therefore the powerful Ps at the output is equal to the product of the voltage
V at exit by intensity I at exit.

Or V = - et I = 3 I

Donc Ps = Vs x Is = - x 3 Ie = Ve x Ie = Pe

Remarque : En utilisant n condensateurs au lieu de trois comme dans l'exemple ci-dessus, le rapport n d'abaissement de tension est égal au nombre n de
Ve condensateurs assemblés, dans ce cas :Vs = e

Le circuit ci-dessus décrit ne permet l'obtention de la puissance Ps à la sortie que pendant la moitiE du cycle du courant alternatif c'est à dire pendant la phase (-) négative où les commutateurs K1 et K2 sont fermées. Pour une utilisation adéquate pendant les deux phases (+) positive et (-) négative du courant alternatif, un circuit double sera envisagé (Fig. 2) dans lequel le double montage du circuit de la Fig. 1 précédemment décrit se fait suivant une disposition rigoureuse.

So Ps = Vs x Is = - x 3 Ie = Ve x Ie = Pe

Note: Using n capacitors instead of three as in the example above, the voltage drop ratio n is equal to the number n of
Ve assembled capacitors, in this case: Vs = e

The circuit described above allows the power Ps to be obtained at the output only during the half of the alternating current cycle, that is to say during the negative (-) phase when the switches K1 and K2 are closed. For an adequate use during the two phases (+) positive and (-) negative of the alternating current, a double circuit will be envisaged (Fig. 2) in which the double assembly of the circuit of Fig. 1 previously described is done according to a rigorous arrangement.
