Definitions
- the invention relates to a circuit for operating a AC high pressure gas discharge lamp for a motor vehicle, with a Ballast, a superimposed ignitor, a symmetrical lamp filter and a high pressure gas discharge lamp, the symmetrical lamp filter between the high pressure gas discharge lamp and the superposition ignition is arranged with a filter capacity parallel to the high pressure gas discharge lamp and a choke in the supply lines to this parallel connection.
- AC high pressure gas discharge lamps such as. B. the Xenon gas discharge lamps for motor vehicles
- Current commutation interference pulses generated by an LC filter combination can be sufficiently suppressed.
- This lamp filter usually exists from a capacitor parallel to the lamp and two inductors in series to the two electrical lamp connections and is in all known cases between the lamp and the actual igniter.
- the disadvantage of this arrangement is that on the returning lamp line, which is not with the ignition transformer is connected, a high voltage pulse arises during ignition, which does not occur when adequate insulation of the lamp overturns according to vehicle mass and can cause significant EMI interference in the vehicle.
- This High voltage pulse drops when igniting at the inductance, which with the returning lamp line is connected. The peak value of the pulse voltage can become very large depending on the design of the lamp filter. In Circuit implementations measure pulse voltages up to 14kV.
- the invention has for its object a circuit for operating a To create AC high pressure gas discharge lamp for a motor vehicle which the voltage level of the impulse voltages mentioned to a harmless Dimension is limited.
- the electrical switching element can advantageously be used as a glow lamp or Switching spark gap must be executed.
- the Circuit according to the invention also has a significantly improved behavior when Ignite a hot lamp because the ignition current is short-circuited Inductance increases faster.
- the single figure shows a ballast for a high pressure gas discharge lamp, and an ignitor with an integrated lamp filter.
- the ballast controls and supplies both the high pressure gas discharge lamp (GDL) as well as the primary ignition circuit of the igniter.
- the ignitor is as one Superimposed ignitor; this is the secondary winding of the Ignition transformer (K1) connected in one of the lamp leads.
- the ignitor also has a symmetrical lamp filter, the symmetrical Lamp filter between the high pressure gas discharge lamp (GDL) and the Superposition ignition is arranged and a filter capacity (C1) parallel to High pressure gas discharge lamp (GDL) and a choke (L1, L2) in each Has feed lines to this parallel connection.
- the choke (L2) in the returning lamp line is an electrical one Switching element connected in parallel.
- This switching element can be used as a glow lamp or Switching spark gap to be formed.
- the training of Switching element as an electronic semiconductor module as practically unsuitable proven, because firstly only particularly expensive, high voltage resistant Semiconductor components come into question, second, semiconductor components one require special control, and thirdly, semiconductor components in the Compared to a glow lamp or switching spark gap relatively high capacity exhibit.
- the switching element becomes conductive and closes due to the ignition voltage pulse this causes the throttle (L2) to be short, so that there is no throttle (L2) High voltage pulse can drop. This will reduce the effort for Isolation of the returning lamp line is reduced, as well as EMI interference this line effectively avoided.
