Definitions

  • the invention relates to the field of power electronics. It is based on a filter circuit arrangement for a converter circuit according to the preamble of the independent claim.
  • Converter circuits in particular with a single-phase or three-phase AC voltage output, which are constructed from switchable power semiconductor switches, such as bipolar transistors with an insulated gate electrode, require filter circuit arrangements to limit the steepness when the switching voltage applied between AC voltage connections of the converter circuit changes.
  • Such a limitation of the steepness of the switching voltage in the event of potential changes is necessary, in particular, in the case of electrical loads such as transformers or electric motors connected to the AC voltage output of the converter circuit, since otherwise asymmetrical stresses on the winding insulation in the transformers or electric motors can occur and bearing damage can also occur when connecting an electric motor.
  • a filter circuit arrangement suitable for reducing resonance vibrations in a line is shown in EP 0473 192 B2.
  • An inductance of the filter circuit arrangement is connected to the AC voltage connections of a three-phase converter circuit.
  • a resistor with a diode is connected between each connection of the individual inductors and the two DC voltage connections of the converter circuit. The resistance with the diode between the respective inductance connections and the two DC voltage connections serves to limit the output current during switching operations of the converter circuit when an electrical load is connected, in particular a motor fed via a long line which is covered with a cable covering.
  • a problem with such a filter circuit arrangement according to EP 0 473 192 B2 is that in order to limit the output current of the converter circuit during switching operations for the inductances of the filter circuit arrangement, extremely large values must be selected in relation to the line inductance of the line in order to be able to achieve a satisfactory limitation of the current.
  • this choice of inductance leads to drastic material costs, an increase in weight and a high space requirement.
  • the filter circuit arrangement does not allow flexible coupling to an electrical load, since the filter components, in particular the inductances, have to be selected and designed as a function of the line to be connected.
  • the filter circuit arrangement is suitable for the suppression of resonance vibrations in a line with an exact design. However, it is unsuitable, for example, for limiting the steepness of the switching voltage in the event of potential changes, which is essential to reduce the electrical and mechanical stress on the components of the electrical load to be connected, when coupled to different loads, since it depends on the boundary conditions specified by the load , Presentation of the invention
  • the object of the invention is therefore to provide a filter circuit arrangement for a converter circuit constructed from power semiconductor switches, which limits the steepness of the switching voltage of the converter circuit in the event of potential changes, can be designed to be load-independent and can be implemented very simply and with few components. This object is solved by the features of the independent claim. Advantageous developments of the invention are specified in the subclaims.
  • the filter circuit arrangement according to the invention for the single-phase or three-phase converter circuit each has at least one inductance at AC voltage connections of the converter circuit, an electrical load being connected to each inductance connection provided on the inductance.
  • a voltage-limiting device is also connected to each inductance connection, and a filter capacitor is also advantageously provided between the inductance connections.
  • the filter capacitor together with the inductance advantageously serves to limit the steepness of the switching voltage, in particular in the event of potential changes.
  • the inductance and the filter capacitor are selected in the filter circuit arrangement such that the resonance frequency of the filter circuit arrangement is substantially greater than the switching frequency of the power semiconductor switches of the converter circuit.
  • the voltage-limiting device also ensures that possible inadmissible overvoltage values in the switching voltage that occur when the steepness of the switching voltage is limited in the event of potential changes are minimized as far as possible.
  • any high-frequency vibrations that occur in the switching voltage which are caused by the design of the filter capacitor and the inductance, are damped by the voltage-limiting device provided at each inductance connection, so that this damping advantageously keeps the high-frequency vibrations away from the electrical load and further reduces the mechanical and electrical stresses.
  • the filter circuit thus also enables improved operational reliability of the connected electrical loads and further circuits possibly involved on the converter output side.
  • the filter circuit arrangement according to the invention represents a particularly simple and inexpensive solution, since it requires only a few components and can therefore be implemented easily and with little expenditure of time.
  • FIG. 1 shows a first embodiment of a filter circuit arrangement according to the invention for a three-phase converter circuit
  • FIG. 2 shows a second embodiment of a filter circuit arrangement according to the invention for a three-phase converter circuit
  • FIG. 3 shows a third embodiment of a filter circuit arrangement according to the invention for a three-phase converter circuit
  • Fig. 4 shows a fourth embodiment of a filter circuit arrangement according to the invention for a three-phase converter circuit.
  • the converter circuit 7 is constructed from power semiconductor switches, which are designed in particular as bipolar transistors with an insulated gate electrode.
  • a common DC voltage intermediate circuit with an intermediate circuit capacitor, which serves as an energy store, is provided at DC voltage connections 8 of the converter circuit 7.
  • the converter circuit 7 has, at its three-phase AC voltage output, AC voltage connections 1 to which at least one inductor 2 is connected in each case. Between the AC voltage connections 1 there is also the switching voltage of the converter circuit 7, which is not shown for the sake of clarity.
  • each inductor 2 according to FIG. 1 has an inductance connection 3 on its load side, to which a common electrical load 6, such as a transformer or an electric motor, is connected.
  • a filter capacitor 5 is provided between the inductance connections 3, each of which has two Inductance connections 3 connects.
  • This filter capacitor 5 forms, together with the inductor 2, a resonance circuit which advantageously limits the steepness of the switching edges of the switching voltage to the desired extent due to its filter action.
  • the inductance 2 and the filter capacitor 5 are selected in such a way that the resonance frequency f res of the filter circuit arrangement is considerably greater than the switching frequency frequency fs of the power semiconductor switch of the converter circuit 7, the resonance frequency f res preferably being in the order of magnitude of 500 times the switching frequency fs.
  • inductors 2 and the filter capacitors 5 are connected with one connection to the inductance connections 3 of the inductors 2 and the other connection of all filter capacitors 5 is connected with one another.
  • the inductor 2 and the filter capacitor 5 are designed in the manner described above makes it possible to set or limit the steepness of the switching voltage when the potential changes to a certain size.
  • electrical stresses for example of insulation windings of a transformer or electrical motor designed as an electrical load 6, are reduced.
  • mechanical stresses in particular in the case of an electric motor connected to the inductance connections 3 as an electrical load 6, are also reduced, for example in the motor bearings and the motor shaft.
  • the design of the inductance and the capacitor is advantageously independent of the load, so that a complex and therefore expensive design adapted to the electrical load can be dispensed with.
  • a voltage-limiting device 4 connected to each inductance connection 3 is provided.
  • This voltage-limiting device 4 ensures that possible inadmissible overvoltage values in the switching voltage which occur when the steepness of the switching voltage is limited when the potential changes are reduced to a minimum.
  • any high-frequency vibrations that occur in the switching voltage, which can occur due to the design of the filter capacitor 5 and the inductor 2 are damped by the voltage-limiting device 4, so that such high-frequency vibrations are advantageously prevented from the electrical load. This enables a further reduction in mechanical and electrical stresses to be achieved.
  • the varistor 1 has at least one varistor, wherein a varistor is advantageously provided between the inductance connections 3 and connects two inductance connections 3.
  • the use of the varistor as a voltage-limiting device 4 has the advantage that a complex voltage-limiting circuitry for the inductance connections 3 with a large number of components can be dispensed with.
  • FIG. 2 shows a second embodiment of the filter circuit arrangement according to the invention.
  • This shows the converter circuit 7 already described in FIG. 1, to which at least one inductance 2 is connected to the AC voltage connections 1 in the manner described above. Furthermore, the filter capacitor 5 and the electrical load are arranged in the manner described.
  • the voltage-limiting device 4 according to FIG. 2 has at least two diodes, each with a resistor connected in series with each diode.
  • the voltage-limiting device 4, in particular the diodes with the resistors connected in series, are connected to the DC voltage connections 8 of the converter circuit 7.
  • the advantage of the voltage-limiting device 4 formed with the diodes with resistors connected in series is that, by suitably selecting the resistor connected in series with the diode, the course of minimizing overvoltage values of the switching voltage while limiting the steepness of the switching voltage in the event of potential changes to specified requirements Converter circuit can be adjusted. For example, it is possible to choose the resistance in such a way that no or only very slight overshoot occurs in the damped switching voltage, which is limited in its steepness. Possible overvoltage values are thus kept away from the connected electrical load 6.
  • the third embodiment of the filter circuit arrangement shown in FIG. 3 differs from the embodiment shown in FIG. 2 in that the voltage-limiting device 4 has at least two diodes connected to the DC voltage connections 8 of the converter circuit 7 via two resistors.
  • the design of the voltage-limiting device 4 is an additional advantage of the voltage-limiting device designed according to FIG. 3.
  • the fact that the resistance connected in series with each diode corresponds to the voltage-limiting device 4 in accordance with FIG Fig. 2 can be saved, which results in a significant cost reduction and a weight and space saving, especially in a three-phase converter circuit.

  • the resistance can be selected in such a way that no or only very slight overshoot occurs in the damped switching voltage, which is limited in its steepness. Overvoltage values that can possibly occur are thereby advantageously prevented from the connected electrical load 6.
  • the filter circuit arrangement according to the invention according to FIGS. 1 to 4 is constructed very simply and with few elements and can be used both for the described three-phase converter circuit 7 according to FIGS. 1 to 4 and for a single-phase converter circuit with a single-phase AC output for limitation the steepness of the switching voltage can be used for potential changes.
