Definitions

  • the invention relates to a frequency converter in which the mains converter is optionally connected to single-phase or single-phase alternating current, the primary winding of a transformer having two secondary windings lying on the alternating voltage, the mains converter consisting of four GTO or IGBT switching poles, two of which are each are connected in parallel.
  • a frequency converter is described in the Siemens publication by A. Weschta "Drive technology for the new high-performance locomotives of the S 252 series of the Spanish Railways", which is suitable for operation with DC and AC voltage. Here, operation with the two supply voltages additional inductors required.
  • the object of the invention is to provide a frequency converter in which no additional inductors are required for operation on different supply systems.
  • the parallel switching poles are connected together via a secondary winding which has a center tap, and in the case of direct current supply the center taps are connected to the intermediate circuit, and in the case of alternating current supply via the transformer the four switching poles are connected in parallel, and that the necessary changes in the connections between direct and alternating current are made by means of switches.
  • the primary winding of the transformer is bridged by means of a switch in the case of direct current supply.
  • the input inductance from the DC power supply and capacitors arranged in parallel with the switching poles form a suction circuit on the intermediate circuit side.
  • Another embodiment of the invention is that a switch for bridging the input inductance at the direct current input, a second switch for separating the two switching poles connected in parallel from the intermediate circuit neutral rail, a third switch for separating the mains converter from the alternating current, and a fourth switch for separating the the switching poles of capacitors connected in parallel from the DC link neutral rail, a fifth switch for separating the DC link capacitors from the DC link neutral rail, a sixth and seventh switch for applying two switching poles connected in parallel to the DC link voltage and an eighth and ninth switch for connecting the DC link is provided with the center taps of the secondary windings with the intermediate circuit.
  • FIG. 1 shows the frequency converter in DC operation and in FIG. 2 the frequency converter in AC operation is shown.
  • Secondary windings T1, T2, of the transformer with the primary winding T placed on the intermediate circuit are connected to the transformer windings T1, T2.
  • the switch 16 short-circuits the winding T in DC operation.
  • the braking point 17 is also arranged in the intermediate circuit.
  • Two three-phase motors 19 are connected to the machine converter 18.

Abstract

Dans un convertisseur de fréquence, dont le convertisseur de courant est connecté, au choix, à un courant continu ou à un courant alternatif monophasé, l'enroulement primaire d'un transformateur (T) présentant deux enroulements secondaires (T1, T2) est connecté à la tension alternative. Le convertisseur de courant comprend quatre pôles de commutation GTO ou IGTB (1, 2, 3, 4) montés en parallèle par paire. Les pôles montés en parallèle (1, 2, 3, 4) sont connectés mutuellement par l'intermédiaire d'un enroulement secondaire (T1, T2) présentant une prise médiane. Pour une alimentation en courant continu, les prises médianes sont connectées au circuit intermédiaire et, pour une alimentation en courant alternatif, les quatre pôles de commutation (1, 2, 3, 4) sont connectés en parallèle via le transformateur (T). Les modifications requises dans les connexions pour alimentation en courant continu et en courant alternatif s'effectuent au moyen d'interrupteurs (7, 8, 9, 10, 11, 12, 13, 14, 15). Le nombre d'interrupteurs se trouve ainsi réduit par économie d'inductances.
