Definitions

  • the invention relates to a converter arrangement for converting a direct voltage into an alternating voltage or another direct voltage and to a test stand with such a converter arrangement.
  • switched inverters are used in particular in test stands for vehicles.
  • the electrical power required for the load machines is made available via a central DC voltage intermediate circuit or a battery, and inverters (so-called machine converters) convert the DC voltage into the AC voltage required for the respective electrical load machine, for example an electric motor.
  • switched DC voltage converters can be provided for generating a DC voltage with a different polarity or a different voltage profile.
  • Such converters can in particular be designed for bidirectional operation (so-called active front end converters), so that they can draw electrical power from the DC voltage intermediate circuit as well as transmit it back.
  • Energy storage capacitors with a very high capacitance are generally arranged in the DC voltage intermediate circuit to stabilize the provided DC voltage. These must be suitable for a DC voltage in the range of around 850 V.
  • the energy storage capacitors used are generally slow capacitors that are not suitable for high frequencies and are usually arranged in the form of their own capacitor banks in a switch cabinet.
  • the length of the supply lines results in relatively large inductances, so that the energy storage capacitors are only slightly loaded by high-frequency interference (ripple currents) with a conventional arrangement.
  • the dynamic test patterns to be tested i.e. the useful signals to be transmitted to the test object
  • have a high frequency for example several hundred Hertz up to 1000 Hz.
  • the energy storage capacitors should be as close as possible be arranged in the switched inverter to enable a compact design.
  • the high-frequency interference generated by the switched inverters affects the energy storage capacitors.
  • One object of the invention is, on the one hand, to ensure that the high-frequency interference is diverted without loading the energy storage capacitors, and, on the other hand, to ensure that the energy storage capacitors can follow the comparatively low-frequency useful signals.
  • the aim is to enable a compact converter arrangement that can be used as a machine converter (DC-AC converter) or direct voltage converter (DC-DC converter) in a test bench for vehicles, without the need for long connecting cables to the energy storage capacitors, without the direct voltage intermediate circuit to disturb and without loading the driven electrical machine with ripple currents.
  • a converter arrangement comprises a DC voltage intermediate circuit for providing a DC voltage VDC, comprising a positive pole and a negative pole, and at least one converter.
  • the converter can be a machine converter (DC-AC converter) for converting the direct voltage VDC into a polyphase alternating voltage. However, it can also be a bidirectionally operated network converter (AC-DC converter) that transfers excess electrical energy from a DC voltage intermediate circuit back into a multi-phase network.
  • the converter according to the invention can also be a direct voltage converter (DC-DC converter) which converts the direct voltage VDC into a direct voltage of a different polarity or different voltage levels.
  • the DC voltage intermediate circuit can have a DC voltage VDC in the range of approximately 850 V or more. In other applications, the DC voltage intermediate circuit can also have a lower DC voltage; for example, when using the converter arrangement according to the invention in a vehicle (automotive sector), a voltage at the intermediate circuit VDC of approximately 48 V can be provided.
  • one or more energy storage capacitors are arranged between the positive pole and the negative pole, a frequency-dependent resistor being arranged in series with the energy storage capacitors, which has a higher electrical resistance at high frequencies than at low frequencies.
  • the frequency-dependent resistance at high frequencies in particular at frequencies above 10 kHz, above 16 kFIz or above 20 kFIz, a multiple, preferably at least a factor of 10, a factor of 12, or a higher factor higher electrical resistance than at low frequencies, in particular at frequencies below 500 Hz.
  • the resistance at frequencies below 500 Hz can in particular be in the milliohm range.
  • the frequency-dependent resistor thus takes on the function of protecting the energy storage capacitors from high-frequency currents, although the specific cut-off frequency can depend on the application.
  • certain applications of the converter arrangement in vehicles can provide limit frequencies of around 150 kFIz, so that the resistance still has a low resistance even at frequencies of around 150 kFIz, and a significantly higher electrical resistance only at frequencies in the range of 2 MFIz accepts.
  • the energy storage capacitor is a particularly storable capacitor with a capacitance of more than 1 mF, preferably 6 mF, for example an electrolytic capacitor.
  • the energy storage capacitors are not designed as electrolytic capacitors, but rather as film or ceramic capacitors. In this application, no electrolytic capacitors are preferably provided.
  • DC voltage intermediate circuit in particular in the case of DC voltages of over 500 V, it can be provided that a first energy storage capacitor and a second energy storage capacitor connected in series are provided.
  • the frequency-dependent resistor can be arranged in series between the first energy storage capacitor and the second energy storage capacitor. It is also possible for more than two energy storage capacitors to be arranged in series. Furthermore, a parallel connection of several energy storage capacitors can also be provided according to the invention.
  • One or more intermediate circuit capacitors that are particularly capable of alternating loads can be arranged parallel to the energy storage capacitor. These serve to divert high-frequency interference, in particular those interference that are generated by the switched inverter.
  • the ratio of the capacitance of the energy storage capacitor to the capacitance of the intermediate circuit capacitors can preferably be greater than 5, particularly preferably greater than 10.
  • the intermediate circuit capacitors can have a capacitance of 180 pF and the energy storage capacitors a capacitance of 1 mF.
  • the intermediate circuit capacitors are designed in the form of film capacitors and / or ceramic capacitors.
  • other types of capacitors are also contemplated according to the invention.
  • the intermediate circuit capacitors can in particular be implemented by connecting individual capacitors in parallel and in series.
  • first intermediate circuit capacitors can be provided as film capacitors with a cut-off frequency of approximately 100 kFIz, and second intermediate circuit capacitors as ceramic capacitors with a cut-off frequency of 1 MFIz and above.
  • the latter can in particular be so-called Cera-Link ceramic capacitors, which have a particularly low inductance at a particularly high cut-off frequency. In this way, a particularly good dissipation of even very high-frequency interference is achieved without loading the energy storage capacitors.
  • the capacitors are designed for a direct voltage of more than 350V, preferably more than 500V, particularly preferably about 850V or about 1400V.
  • the intermediate circuit voltage is significantly lower, for example in the range of 48 V, and the switching frequencies are significantly higher, so that according to the invention only ceramic capacitors and film capacitors are used, not electrolytic capacitors.
  • the first and / or second intermediate circuit capacitors can be provided as film capacitors or ceramic capacitors with a cutoff frequency in the range of approximately 2 MFIz.
  • two energy storage capacitors connected in series are provided, which are arranged on a printed circuit board or another carrier, the frequency-dependent resistor being arranged between these components, namely on the underside of the printed circuit board or the carrier.

  • the diameter D can vary periodically along the longitudinal extent L by a mean value Do +/- AD, wherein Do is preferably approximately 10 mm and AD is preferably approximately 1 mm.
  • a direct voltage source providing the direct voltage VDC can be provided, for example a battery or a network converter in the form of a switched rectifier which is designed to convert a polyphase network voltage into a direct voltage.
  • the invention further comprises a test stand for a vehicle or any drive, for example an industrial drive with a converter arrangement according to the invention.
  • a test stand can comprise a network converter, a converter arrangement according to the invention and an electrical machine driven by the alternating voltage generated.
