Definitions

  • the purpose of the present invention patent application is a new filter of the so-called "common mode" used to eliminate disturbances or noise in electrical circuits.
  • the filter that the invention proposes is intended to filter the electrical noise coming from the power and signal lines to the protected circuit, as well as minimizing the interferences that could be generated in conducted mode.
  • the object of the present invention is a device for controlling doors in the railway environment using said filter.
  • the switched power supplies incorporate a common mode filter to eliminate the interference led to the power supply. These filters are used in the power lines.
  • the common mode filter In the case of continuous feeding, the common mode filter consists of two coils, one in each supply wire, coupled on the same magnetic core. In the case of three-phase feeders, the common mode filter is made up of three coils, one in each supply wire, coupled on the same magnetic core. Finally, the feed systems based on tripoli (one input wire, one output and one common return), as in three-phase systems, the common mode filter consists of three coils, one in each feed wire, coupled on the same magnetic core, as described in European patent EP1487092.
  • the transformer will act generating voltages in its windings to try to compensate for the imbalance of currents. These tensions, which can become very high, will manifest themselves in the form of electrical noise peaks that will appear in the control and power lines.
  • Figure 2A shows how when the switch S1 is open and switch S2 is also open, the current balance is fulfilled by the coils in common mode (L1 of a first device A and L2 of a second device B). Therefore:
  • coils L1 and L2 tend to match the currents by their windings they generate a voltage VL1 and VL2 to oppose this increase in current.
  • coils L1 and L2 tend to saturate. If it is assumed that L2 is the one that is previously saturated (by constructive dispersions), the influence thereof disappears, which causes the potential of point A to be superior to that of point B, and the appearance of a current 17. This current is interpreted by equipment B as if switch S1 were closed, causing equipment B to act abnormally.
  • the common mode filter that the present invention proposes solves the aforementioned drawbacks, becoming an effective and economical alternative.
  • the common mode filter of the invention is materialized in such a way that it comprises, in addition to the coils corresponding to each feed wire (continuous, alternating, three-phase and tripoli), an extra coil for each of the control lines or external signals with reference to the common power return prior to the filter.
  • the filter of the invention is structured so that, as already mentioned, it includes an extra coil for each of the external signals with reference to the common power return.
  • the filter of the invention when introducing the signal lines referenced to the external power supply in the common mode filter, the sum of the input and output currents will be balanced, leaving all the filtered lines of electrical noise conducted in mode common when the currents remain by the different windings of the compensated coils, making sure that the filter works correctly and that the undesired tensions in the control lines and the interactions with other devices disappear.

  • Figures 2A, 2B and 2C- They show three diagrams or schematic circuits of the common mode filters of the state of the art for the particular case in which two parallel connected devices are to be protected.

  • control signals can be both input and output, for example in the case where it is necessary to command external loads from the control equipment, even with different potential references, provided that all lines are filtered of electrical noises conducted in common mode when the currents (H, 12, 13 and 14) remain by the different windings of the coils (L1, L2, L3 and L4) compensated, making sure that the filter works correctly and disappears the unwanted tensions in control lines and interactions with other devices.
  • the two control lines (3) and (4) have no negative effect on the filter when the currents remain due to the different windings of the coils (L3) and (L4) compensated.
  • the filter of the invention is capable of being extended in case there are n control lines (1, 2, ... n) for a circuit (5) or electronic equipment, according to the needs of each application.
  • Figure 5 shows a possible physical embodiment of a common mode filter of the invention in the case that there are 2 windings as feed lines (7,8) and 3 windings as control lines (9, 10, 1 1) referenced to the feed. All lines (7, 8, 9, 10 and 1 1) are magnetically coupled to each other through a magnetic core (12), wherein said magnetic core (12) may be toroidal in shape, or in any other way as E, U, I cores, etc.
  • the magnetic core (12) may also be formed by joining several toroids of different permeability to achieve attenuations at different frequencies.
  • the windings of the inductances can be made of different sections depending on the current flowing through them.
  • a door control device specifically, for the control of opening doors, for example in the railway field, where said door is commanded by a door control unit (13) or CPU, shown schematically in Figure 6, where the problems indicated in the current state of the art may appear, that is, where said door control units (13) are fed by the same power supply ( 6), typically 1 10 volts, which share two control lines (1) and (2), one for

Abstract

L'invention concerne un filtre en mode commun et un dispositif de commande de portes de véhicules ferroviaires faisant appel à ce filtre. Ledit filtre sert à filtrer les bruits électriques provenant des lignes d'alimentation et des signaux. De manière générale, il est conçu de façon que les lignes de commande (1, 2, 3, 4) extérieures référencées par rapport au retour d'alimentation commun comprennent une bobine, ce qui permet d'équilibrer la somme des courants d'entrée et de sortie dudit filtre.
