Definitions

  • the present invention relates to means adapted for forming electronic converters which, fed from the AC mains, are able to take only a perfectly sinusoidal current which is perfectly in phase with the voltage, even if the load applied at the output of these converters has a reactive term or non linear impedance, as is the case for example for a fluorescent discharge lamp.
  • Such devices are only a palliative which makes it possible to comply, under very precise and specified conditions, with the less constraining standards which govern rejection of the harmonic currents in the mains.
  • These devices are incapable of accepting any type of load, resistive such as a simple lamp, inductive such as an electric motor, capacitive such as the rectifier circuit of a stabilized power supply and non linear such as a fluorescent lamp, without causing considerable distortion of the current taken from the mains.
  • the device of the invention overcomes these drawbacks, which restrict the generalized use of such devices, especially when it is a question of installations comprising a large number of units, such as is the case in fluorescent lighting.
  • This device simple to construct, eradicates practically completely the harmonic currents which it would be capable of rejecting in the mains, over an input voltage range from -60% to +30% of the rated value, whereas international standards set a range of -10% to +10%. Furthermore, this device accepts at the output any type of load, resistive, inductive, capacitive or non linear without appreciable distortion of the current taken from the mains.
  • the device comprises an electronic chopping converter whose biased input is shunted by a buffer circuit formed by at least two capacitors capable of being charged in series by the mains current supply line and capable of being discharged in parallel across the input of said converter, said buffer.-circuit is itself loaded by two rectifier circuits mounted so that the addition of their output signals occt&rs at the level of said buffer circuit and the input of said converter.
  • the input of the first rectifier circuit is fed by the AC mains whereas the input of the second rectifier circuit is fed by a fraction of the high frequency energy delivered at the output of said converter.
  • the common point to one and other rectifier circuit is high frequency decoupled by a capacitor connected between said common point and the input terminals. of said converter.
  • the current taken from the mains is applied between the terminals la and lb which are connected, through the HF filter formed by the two symmetrical inductances 2a and 2b, to the unbiased input of the rectifier bridge whose biased output is connected in series with the biased output of the second rectifier bridge 4, so that a suitably biased current may flow freely through the series circuit thus formed.
  • Said biased series circuit charges the input terminals 9a and 9b of the converter 10, between which a buffer circuit is connected comprising any number of suitably biased capacitors which are capable of being charged in series by said rectifier circuit and discharged in parallel across the input of converter 10.
  • the number of capacitors used is limited to 5 capacitors 5a, 5b, 5c, 5d and 5e. These capacitors are charged in series by means of the rectifier circuits 3 and 4 through the suitably biased diodes 6a, 6b, 6c and 6d which connect together in series, respectively, the above capacitors two by two. So that each of the capacitors thus charged in series may be discharged between terminals 9a and 9b, two series of suitably biased diodes 7a, 7b, 7c, 7d and 8a, 8b, 8c, 8d are used which provide this function. Thus, capacitor 5a may be discharged through diodes 8a, 8b, 8c and 8d mounted in series and suitably biased.
  • Capacitor 5b may be discharged through the series of suitably biased diodes 7a, ' 8a, 8c and 8d.
  • Capacitor 5c may be discharged through the series of suitably biased diodes 7a, 7b, 8c and 8d.
  • the capacitor 5d may be discharged through the series of suitably biased diodes 7a, 7b, 7c and 8d.
  • capacitor 5e it may be discharged through the series of suitably biased diodes 7a, 7b, 7c and 7d.
  • the AC mains current charges the capacitors cyclically in series, which may be discharged in parallel across the input terminals of converter 10, which may thus begin to operate.
  • converter 10 is able to deliver between its subsidiary output terminals 11a and lib a signal of suitable amplitude, which is applied to the unbiased input of rectifier 4 so that a fraction of the high frequency energy converted by the latter is rectified at the output of rectifier 4 and added to the envelope, itself rectified, of the mains voltage.
  • a signal of suitable amplitude which is applied to the unbiased input of rectifier 4 so that a fraction of the high frequency energy converted by the latter is rectified at the output of rectifier 4 and added to the envelope, itself rectified, of the mains voltage.
  • capacitor 13 connected between one of terminals 9a or 9b and the common point to rectifiers 3 and 4, is to provide high frequency decoupling of said common point.
  • This device makes possible the feeding of converter 10 with a low ripple rate and not charging directly from the mains an electrolytic capacitor of high value, only taking therefrom a perfectly sinusoidal current, over a wide input voltage range and a wide range of variation of the impedance connected at the output of converter 10. Furthermore, this device is compatible with a DC network where it may be advantageous to the extent that the buffer circuit formed by capacitors 5a, 5b, 5c, 5d and 5e represents an excellent means of filtering all the high frequency parasite rejects which might be present between terminals 9a and 9b.
  • the high frequency rectifier circuit is a circuit of "doubler" type comprising diodes 4a and 4b whose input is loaded by capacitor 15, and said diode 6a, charging capacitors 5a and 5b in series, is split into diodes 14a and 14b also connected as a doubler whose input is high frequency loaded by the input 11a of the primary 11 of transformer 16 which, with transistors 17a and 17b, are the only members of said converter 10 shown here.
  • the middle point of diodes 14a and 14b is also connected to capacitor 18 whose value is chosen so that the oscillating circuit which it forms with the primary 11 has a resonance frequency very close to the parallel resonance frequency of the oscillating circuit comprising the secondary 12 associated with capacitor 19.
  • the excess energy is located between the terminals of primary 11 and especially between the terminals of capacitor 18 , which the voltage doubler formed by diodes 14a and 14b charges, which results in re-transforming the high frequency energy into DC energy which may then be re ⁇ stored respectively in capacitor 5a and 5b, via the suitably biased diodes 7a and 7b.
  • the high frequency energy for smoothing the rectified voltage present between terminals 9a and 9b by addition to the rectified mains voltage is taken between terminals 11a and lib of primary 11.
  • the output lib is suitably situated on the primary winding 11 so that capacitor 15, connected between the output lib and the input of the voltage doubler formed by diodes 4a and 4b, derives a voltage in addition to the mains voltage exactly adapted to smoothing of the voltage present at terminals 9a and 9b. It is also possible to dose the amplitude of said additional voltage re-injected at the input by choosing a suitable value of capacitor 15, whose high frequency reactance considered ensures the adjustment.
  • Capacitors 5a and 5b are charged in series, via the suitably biased diodes 4a and 4b, by means of the biased output of the mains rectifier 3 which is mounted in series with the biased output of the doubler bridge comprising diodes 4a and 4b. Parallel discharge across the terminals 9a and 9b of capacitor 5a and capacitor 5b takes place, respectively, by means of diode 8a and diode 7a.
  • the useful converted energy is available between the output terminals 12 a and 12b representing the secondary of transformer 16.
  • the doubler bridge comprising diodes 4a and 4b could be replaced .by a pump rectifier comprising any number of stages or by a single rectifier stage, and the winding corresponding to outputs 11a and lib could be independent of the primary 11.
  • the secondary 12 could be not separate from primary 11, the transformer 16 then being of the self- transformer type.
  • the device of the invention may be used in association with most converter structures.
  • This device makes it possible to supply such a converter, from an AC network, with a rectified current having only a low ripple rate, without altering the power factor of the current taken from the mains or causing it to undergo an appreciable harmonic distortion.
  • this device makes it possible to connect any type of load, inductive, capacitive or more generally non linear to the output thereof, without appreciably altering the characteristics of the current taken from the mains.
  • the device of the invention may be used in all cases where it is desired to provide an economic and reliable power supply for any electronic converter for electronic ballast, electronic transformer, stabilized power supply use etc...

Abstract

L'invention se rapporte à un dispositif économique servant à l'alimentation d'un convertisseur électronique à partir du secteur, sans que le courant prélevé sur le secteur soit affecté par une distorsion notable due aux harmoniques, quelle que soit la nature de la charge s'appliquant à la sortie du convertisseur. Un tel dispositif comprend un circuit tampon formé par au moins deux condensateurs (5a et 5b) chargés par le secteur, en série et déchargé chacun en parallèle à travers les bornes d'entrée (9a et 9b) du convertisseur (10). Dès que ce dernier se met à fonctionner, une fraction de l'énergie HF de sortie est rectifiée par le pont, qui ajoute son signal de sortie à celui délivré par le premier pont (3). Ainsi, la tension d'alimentation présente au niveau des bornes (9a et 9b) ne présente qu'un taux d'ondulation efficace réduit, tandis que le courant prélevé sur le secteur est essentiellement sinusoïdale en phase avec la tension, quelle que soit la nature de la charge s'appliquant à la sortie, résistive, inductive, capacitive ou non linéaire. Un tel dispositif peut s'appliquer à la plupart des convertisseurs électroniques utilisés comme ballasts, comme transformateurs, comme sources d'alimentation stabilisées, etc.
