Definitions

  • the object of the invention is therefore to provide a method which is equipped with two parallel paths for the energy flow, so that an interruption in the supply of the load impedance is never necessary.
  • the supply voltage source if the reserve voltage source fails, the supply voltage source is reconnected to the first winding part, so that the operating voltage U3 of the load impedance is generated again via the supply voltage source. As a result, if the reserve voltage source fails, the supply voltage source takes over the supply again without an interruption.
  • the control unit 6 brings the current operating parameters of the supply voltage source present at one of its inputs into correspondence with the output voltage U2 of the inverter 2 via one of its outputs, in that the phase and frequency thereof correspond to the corresponding values of the supply Voltage source U j are brought and zero phase difference and frequency equality between U j and U2 is established.
  • a second secondary winding 34 is connected to a rectifier unit 8, the output of which is connected to the battery unit 1 as a charging source.
  • This charging of the batteries takes place only at times when a normal operating state with the operating parameters of the supply voltage source 3 prevails within the permitted range, while the rectifier unit 8 is separated from the second secondary winding 34 in the event of an emergency supply.

Abstract

L'invention concerne un procédé d'alimentation électrique ininterrompue d'une impédance chargée, à l'aide d'une source de tension d'alimentation. Les paramètres de fonctionnement de la tension de sortie de la source de tension d'alimentation sont mesurés en continu par une unité de commande. On réalise une alimentation de secours parallèle dans la mesure où lorsque les paramètres de fonctionnement se trouvent dans la fourchette des valeurs limites, la tension de sortie U2 de la source de tension de réserve (1, 2) pilotable au moyen de l'unité de commande (6) est amenée dans une première étape à la même fréquence et à la même position de phases que la tension de sortie U1 de la source de tension d'alimentation (3). Une tension de fonctionnement U3 = U1.N3/N1 est alors produite pour actionner l'impédance chargée (7). La tension de sortie U2 est maintenue par l'unité de commande (6) approximativement au même niveau que U2 = U3.N2/N3, sans être cependant exactement au même niveau ou au-dessus, de manière à ce qu'en cas de défaillance de la source de tension d'alimentation (3), la tension de fonctionnement U3 de l'impédance chargée reste maintenue uniquement par la source de tension de réserve (1, 2).
